Cortisol - ein geeigneter physiologischer Indikator für Belastungen am Arbeitsplatz?

Die vorliegende Studie prüft Zusammenhänge zwischen Arbeitsintensität, Tätigkeitsspielraum, sozialer Arbeitsumgebung (Kooperation/Kommunikation, soziale Unterstützung, soziale Stressoren) und Stresserleben am Arbeitsplatz mit der basalen Cortisolsekretion im Speichel (Tagesprofil, Aufwachreaktion und Variation über den Tag). Insgesamt 46 Erwerbstätige aus dem Bankwesen sammelten an zwei aufeinander folgenden Arbeitstagen je vier Speichelproben (beim Aufwachen, 30 min nach dem Aufwachen, 14 Uhr und unmittelbar vor dem Zubettgehen), aus denen die individuelle Cortisolkonzentration (Mittelwert aus den jeweils zugehörigen Proben) bestimmt wurde. Die Tätigkeitsmerkmale wurden sowohl mittels Fragebögen als auch objektiv, d.?h. unabhängig vom Arbeitsplatzinhaber, erhoben. Alter, Geschlecht, Rauchen, Body-Mass-Index, gesundheitliche Beeinträchtigungen sowie eventuelle Abweichungen bei der Probensammlung wurden als mögliche Drittvariablen berücksichtigt. Im Ergebnis zeigte sich, dass subjektiv erlebte, geringe soziale Unterstützung und hohe soziale Stressoren mit einer erhöhten Aufwachreaktion bzw. mit einer erhöhten Variation über den Tag assoziiert waren. Für die Arbeitsintensität, den Tätigkeitsspielraum sowie für die objektiv erhobene Kooperation/Kommunikation waren keine Effekte nachweisbar. Die Ergebnisse lassen vermuten, dass sowohl die Belastungs- als auch deren Erhebungsart für den Nachweis von Effekten im Hinblick auf die Cortisolsekretion bei Erwerbstätigen von Bedeutung sind. The present study examines associations between job demands, job control, social work environment (cooperation/communication, social support, social stressors), and strain at work with basal salivary cortisol (day profiles, cortisol awakening reaction, diurnal variation). Forty-six employees collected four saliva samples (immediately after waking up, 30 min after waking up, at 2 p.m. and immediately before going to bed) each on two consecutive working days. We computed the mean across the two days for each of the four saliva samples per employee. Job characteristics were assessed by self-reports as well as by objective job analysis. Analyses were controlled for possible confounding effects of age, gender, smoking, body-mass index, health impairments, and non compliance with the cortisol protocol. Results show that subjectively experienced low social support and high social stressors at work were associated with elevated cortisol awakening reaction and elevated diurnal variation. We found no effects for job demands, job control or objectively assessed cooperation/communication. Our results suggest that both the type of job characteristic as well as the type of measurement of job characteristics have to be taken into account when relating them to employees’ cortisol secretion.

Psychosoziale Merkmale der Arbeit, Überforderungserleben und Depressivität

Die vorliegende Studie untersuchte die im Job-Demand-Control-Support-Modell und Effort-Reward-Imbalance-Modell beschriebenen Tätigkeitsmerkmale in Bezug auf Depressivität in einer Stichprobe von 265 Erwerbstätigen. Anhand konfirmatorischer Faktorenanalysen wurden Gemeinsamkeiten und Unterschiede beider Modelle geprüft. Anschließend wurde die Bedeutung der nachweisbaren Tätigkeitsmerkmale für die Vorhersage von Depressivität getestet und untersucht, inwieweit die Effekte durch Überforderungserleben mediiert werden. Die Analysen zeigten, dass die Modelle sowohl gemeinsame (Arbeitsintensität bzw. berufliche Anforderungen) als auch distinkte Arbeitsmerkmale (Tätigkeitsspielraum, Arbeitsplatzsicherheit, beruflicher Status, soziale Anerkennung) erfassen. Hohe Arbeitsintensität, geringe Arbeitsplatzsicherheit und fehlende soziale Anerkennung standen in signifikantem Zusammenhang mit Depressivität. Anders als erwartet war der berufliche Status positiv mit Depressivität assoziiert, während für den Tätigkeitsspielraum keine signifikanten Effekte nachweisbar waren. Das Pfadmodell bestätigte sowohl direkte als auch durch Überforderungserleben vermittelte Zusammenhänge zwischen den Tätigkeitsmerkmalen und Depressivität (39 % Varianzaufklärung). Die Ergebnisse bieten eine Grundlage für die Identifizierung potenzieller Risikofaktoren für das Auftreten depressiver Symptome am Arbeitsplatz. This study examined the job characteristics in the Job-Demand-Control-Support Model and in the Effort-Reward Imbalance Model with regard to depression in a sample of 265 employees. First, we tested by means of confirmatory factor analysis similarities and differences of the two models. Secondly, job characteristics were introduced as predictors in a path model to test their relation with depression. Furthermore, we examined whether the associations were mediated by the experience of excessive demands. Our analyses showed the demand/effort component to be one common factor, while decision latitude and reward (subdivided into the three facets of job security, social recognition, and status-related reward) remained distinctive components. Employees with high job demands/effort, low job security, low social recognition, but high status-related rewards reported higher depression scores. Unexpectedly, status-related rewards were positively associated with depression, while we found no significant effects for decision latitude. The path models confirmed direct as well as mediation effects (through experienced excessive demands) between job characteristics and depression (39 % explained variance in depression). Our results could be useful to identify possible job-related risk factors for depression.

Knowledge workers and their relationships with organisations

The programme of research examines knowledge workers, their relationships with organisations, and perceptions of management practices through the development of a theoretical model and knowledge worker archetypes. Knowledge worker and non-knowledge worker archetypes were established through an analysis of the extant literature. After an exploratory study of knowledge workers in a small software development company the archetypes were refined to include occupational classification data and the findings from Study 1. The Knowledge Worker Characteristics Model (KWCM) was developed as a theoretical framework in order to analyse differences between the two archetypes within the IT sector. The KWCM comprises of the variables within the job characteristics model, creativity, goal orientation, identification and commitment. In Study 2, a global web based survey was conducted. There were insufficient non-knowledge worker responses and therefore a cluster analysis was conducted to interrogate the archetypes further. This demonstrated, unexpectedly, that that there were marked differences within the knowledge worker archetypes suggesting the need to granulate the archetype further. The theoretical framework and the archetypes were revised (as programmers and web developers) and the research study was refocused to examine occupational differences within knowledge work. Findings from Study 2 identified that there were significant differences between the archetypes in relation to the KWCM. 19 semi-structured interviews were conducted in Study 3 in order to deepen the analysis using qualitative data and to examine perceptions of people management practices. The findings from both studies demonstrate that there were significant differences between the two groups but also that job challenge, problem solving, intrinsic reward and team identification were of importance to both groups of knowledge workers. This thesis presents an examination of knowledge workers’ perceptions of work, organisations and people management practices in the granulation and differentiation of occupational archetypes.

Do women earn less even as social entrepreneurs? The gender pay gap among UK social enterprise directors

Based upon unique survey data collected using respondent driven sampling methods, we investigate whether there is a gender pay gap among social entrepreneurs in the UK. We find that women as social entrepreneurs earn 29% less than their male colleagues, above the average UK gender pay gap of 19%. We estimate the adjusted pay gap to be about 23% after controlling for a range of demographic, human capital and job characteristics, as well as personal preferences and values. These differences are hard to explain by discrimination since these CEOs set their own pay. Income may not be the only aim in an entrepreneurial career, so we also look at job satisfaction to proxy for non-monetary returns. We find female social entrepreneurs to be more satisfied with their job as a CEO of a social enterprise than their male counterparts. This result holds even when we control for the salary generated through the social enterprise. Our results extend research in labour economics on the gender pay gap as well as entrepreneurship research on women’s entrepreneurship to the novel context of social enterprise. It provides the first evidence for a “contented female social entrepreneur” paradox.

Relative importance of false positives in the selection process

This study investigated the role of contextual factors in personnel selection. Specifically, I explored if specific job factors such as the wage, training, available applicant pool and security concerns around a job, influenced personnel decisions. Additionally, I explored if the individual differences of decision makers played a role in how the previously mentioned job factors affected their decisions. A policy-capturing methodology was employed to determine the weight participants place on the job factors when selecting candidates for different jobs. Regression and correlational analyses were computed with the beta weights obtained from individual regression analyses. The results obtained from the two samples (student and general population) revealed that specific job characteristics did indeed influence personnel decisions. Participants were more concerned with making mistakes and thus less likely to accept candidates when selecting candidates for jobs having high salary and/or high training requirements.

Women Hospitality Managers: Perceptions of Gender-Related Career Challenges

In spite of increases in the number of women who are both academically pre- pared and interested in pursuing hospitality management careers, women appear to be leaving the industry at a much higher rate than their male counter- parts. Although women are better represented in lower and middle management than ever before, there has been no corresponding increase in the number of women in top level management positions. The author explores women managers' perceptions of the career-related challenges they confront in hospitality environments and suggests that inadequate access to informal information networks, lack of women mentors, and the impact of unique job characteristics are their most significant concerns.

Género, idade e antiguidade na empresa : Uma análise comparativa de contracto psicológico.

Poucos são os estudos que relacionam variáveis de nível individual como o género, idade e antiguidade na empresa, com a percepção de contracto psicológico, no entanto para além destas variáveis moldarem o conteúdo do contracto psicológico (Guest, 2004), parecem também determinar diferentes valores e interesses de trabalho (Elizur, 1994; Bal, Lange, Jansen e Velde, 2008). Tais evidências chamam a atenção das organizações para o facto de diferentes grupos de trabalhadores apresentarem diferentes percepções de contracto psicológico, podendo consequentemente responder de diferente forma às mesmas políticas organizacionais (Freese & Schalk, 1996). O presente estudo procurou perceber se diferentes grupos de trabalhadores, de diferentes géneros, idades e antiguidades apresentam diferentes percepções de contracto psicológico, procurando posteriormente aceder às causas percebidas de quebra de contracto (Renegação, Disrupção, Incongruência e Anulação), mencionadas na literatura por Rousseau (1995) e Morrinson e Robinson (1997). Foi utilizada uma amostra, recolhida por conveniência, de 83 participantes pertencentes a uma empresa do sector alimentar, constituída por 57,8% de mulheres e 42,2% de homens. Em média possuem 37 anos de idade e 9 anos de antiguidade na empresa. Foi aplicado um questionário, desenvolvido por Lester, Turnley, Bloodgood e Bolino (2002) constituído por diferentes dimensões (Compensação, Recompensas com base na performance, Características da Função, Progressão e Desenvolvimento, Recursos e Relação Laboral) que constituem o contracto psicológico, assim como pelas diferentes causas percebidas de incumprimento da promessa. Após uma análise factorial, foram extraídos 5 factores (Características da Função, Relação Laboral, Compensação, Recursos e Progressão e Recompensas com base na performance). Os resultados demonstraram que os trabalhadores mais velhos percepcionam que a sua empresa lhes proporciona menos do que o prometido relativamente à Compensação, resultados igualmente obtidos para os trabalhadores com mais antiguidade na empresa. Uma posterior análise correlacional demonstrou que a idade está associada com a antiguidade dos trabalhadores. Quanto à causa percebida de incumprimento, os resultados evidenciaram que a maioria dos trabalhadores atribui o incumprimento das promessas à Renegação. Por outras palavras, os trabalhadores entendem que a sua organização não cumpriu as promessas que lhes fez, simplesmente porque assim o quis.

An application of an extended effort-reward imbalance model to police absenteeism behaviour

Purpose – Frequent absences from work can be highly disruptive, whilst also potentially indicating problematic working conditions that can lead to increased withdrawal behaviour. The purpose of this paper is to test the predictive capability of an expanded effort-reward imbalance model on employee absenteeism within the context of policing.

Design/methodology/approach – Three separate reward systems are identified by the effort-reward imbalance model. In this study, the authors assessed these individual components for their contribution to officer withdrawal behaviour in the form of absenteeism frequency. Data were gathered from a sample of operational officers (n=553) within a large Australian police agency.

Findings – Findings indicate that there was a strong influence of social rewards such as social support and recognition in the workplace on officer absenteeism rates. Low workload was associated with a higher frequency of absenteeism suggesting a potential underloading effect. There were a number of significant interactions providing support for the effort-reward imbalance mechanism and the separation of the reward construct. Security rewards were particularly influential and significantly moderated the relationship between effort and absenteeism.

Research limitations/implications – Differential effects of occupational rewards were identified in the study, indicating that there are significant opportunities for expansion of the effort-reward imbalance model along with opportunities for HRM practitioners in terms of employee recognition and remuneration programmes. This research was focused on a specific sample of operational officers, therefore should be expanded to include multiple occupational groups.

Originality/value – This paper considers and expanded model of worker strain and contributes a longitudinal assessment of the association between perceived effort and reward systems and worker absenteeism.

Low control and high demands at work as risk factors for suicide: An Australian national population-level case-control study

OBJECTIVES: Previous research suggests that psychosocial job stressors may be plausible risk factors for suicide. This study assessed the relationship between psychosocial job stressors and suicide mortality across the Australian population. METHODS: We developed a job exposure matrix to objectively measure job stressors across the working population. Suicide data came from a nationwide coronial register. Living controls were selected from a nationally representative cohort study. Incidence density sampling was used to ensure that controls were sampled at the time of death of each case. The period of observation for both cases and controls was 2001 to 2012. We used multilevel logistic regression to assess the odds of suicide in relation to 2 psychosocial job stressors (job control and job demands), after matching for age, sex, and year of death/survey and adjusting for socioeconomic status. RESULTS: Across 9,010 cases and 14,007 matched controls, our results suggest that low job control (odds ratio [OR], 1.35; 95% confidence interval [CI], 1.26-1.44; p < .001) and high job demands (OR, 1.36; 95% CI, 1.26-1.46; p < .001) were associated with increased odds of male suicide after adjusting for socioeconomic status. High demands were associated with lower odds of female suicide (OR, 0.81; 95% CI, 0.72-0.92; p = .002). CONCLUSIONS: It seems that adverse experiences at work are a risk factor for male suicide while not being associated with an elevated risk among females. Future studies on job stressors and suicide are needed, both to further understand the biobehavioral mechanisms explaining the link between job stress and suicide, and to inform targeted prevention initiatives.

Supervision practices in allied mental health : relationships of supervision characteristics to perceived impact and job satisfaction

This study examined whether supervision characteristics impacted on mental health practice and morale, and developed a new Supervision Attitude Scale (SAS). Telephone surveys were conducted with a representative sample of 272 staff from public mental health services across Queensland. Although supervision was widely received and positively rated, it had low average intensity, and assessment and training of skills was rarely incorporated. Perceived impact on practice was associated with acquisition of skills and positive attitudes to supervisors, but extent of supervision was related to impact only if it was from within the profession. Intention to resign was unrelated to extent of supervision, but was associated with positive attitudes to supervisors, accessibility, high impact, and empathy or praise in supervision sessions. The SAS had high internal consistency, and its intercorrelations were consistent with it being a measure of relationship positivity. The study supported the role of supervision in retention and in improving practice. It also highlighted supervision characteristics that might be targeted in training, and provided preliminary data on a new measure.

Speeding by young novice drivers : what can personal characteristics and psychosocial theory add to our understanding?

Purpose: Young novice drivers continue to be overrepresented in fatalities and injuries arising from crashes even with the introduction of countermeasures such as graduated driver licensing (GDL). Enhancing countermeasures requires a better understanding of the variables influencing risky driving. One of the most common risky behaviours performed by drivers of all ages is speeding, which is particularly risky for young novice drivers who, due to their driving inexperience, have difficulty in identifying and responding appropriately to road hazards. Psychosocial theory can improve our understanding of contributors to speeding, thereby informing countermeasure development and evaluation. This paper reports an application of Akers’ social learning theory (SLT), augmented by Gerrard and Gibbons’ prototype/willingness model (PWM), in addition to personal characteristics of age, gender, car ownership, and psychological traits/states of anxiety, depression, sensation seeking propensity and reward sensitivity, to examine the influences on self-reported speeding of young novice drivers with a Provisional (intermediate) licence in Queensland, Australia. Method: Young drivers (n = 378) recruited in 2010 for longitudinal research completed two surveys containing the Behaviour of Young Novice Drivers Scale, and reported their attitudes and behaviours as pre-Licence/Learner (Survey 1) and Provisional (Survey 2) drivers and their sociodemographic characteristics. Results: An Akers’ measurement model was created. Hierarchical multiple regressions revealed that (1) personal characteristics (PC) explained 20.3%; (2) the combination of PC and SLT explained 41.1%; and (3) the combination of PC, SLT and PWM explained 53.7% of variance in self-reported speeding. Whilst there appeared to be considerable shared variance, the significant predictors in the final model included gender, car ownership, reward sensitivity, depression, personal attitudes, and Learner speeding. Conclusions: These results highlight the capacity for psychosocial theory to improve our understanding of speeding by young novice drivers, revealing relationships between previous behaviour, attitudes, psychosocial characteristics and speeding. The findings suggest multi-faceted countermeasures should target the risky behaviour of Learners, and Learner supervisors should be encouraged to monitor their Learners’ driving speed. Novice drivers should be discouraged from developing risky attitudes towards speeding.

High-growth firms : characteristics, job contribution and method observations

Largely as a result of mass unemployment problems in many European countries, the dynamics of job creation has in recent years attracted increased interest on the part of academics as well as policy-makers. In connection to this, a large number of studies carried out in various countries have concluded that SMEs play a very large and/or growing role as job creators (Birch, 1979; Baldwin and Picot, 1995; Davidsson, 1995a; Davidsson, Lindmark and Olofsson, 1993; 1994; 1995; 1997a; 1997b; Fumagelli and Mussati, 1993; Kirchhoff and Phillips, 1988; Spilling, 1995; for further reference to studies carried out in a large number of countries see also Aiginger and Tichy, 1991; ENSR, 1994; Loveman and Sengenberger, 1991; OECD, 1987; Storey and Johnson, 1987). While most researchers agree on the importance of SMEs, there is some controversy as regards whether this is mainly a result of many small start-ups and incremental expansions, or if a small minority of high growth SMEs contribute the lion’s share of new employment. This is known as the ‘mice vs. gazelles’ or ‘flyers vs. trundlers’ debate. Storey strongly advocates the position that the small group of high growth SMEs are the ‘real’ job creators (Storey, 1994; Storey & Johnson, 1987), whereas, e.g., the Davidsson et al research in Sweden (cf. above) gives more support for the ‘mice’ hypothesis.
