Conflicts in the workplace, negative acts and health consequences: evidence from a clinical evaluation.

Interpersonal conflicts at workplace are increasing in relation to high competitiveness and pressures at work, mainly connected with labor market globalization. Their manifestation is multifaceted in relation to different working conditions and they not only hinder health, performance, and job satisfaction, but can also harm people's rights and dignity. The study analyses issues related to work conflicts and adverse health consequences in 1,493 workers who approached a hospital service for work-related stress and harassment over a 3-year period. The subjects were examined according to a broad protocol covering working conditions, sources of conflict and negative actions suffered, and resulting impact on health status. Many critical conditions were reported in all occupational sectors with some differentiation in relation to gender (women more at risk) and employment status. Higher qualified levels were more exposed to experiencing severe personal adversities aimed at their progressive expulsion or resignation, with consequent higher risk of chronic adjustment disorders, while lower levels reported more stressful conditions in terms of interpersonal disputes and greater interference in the home-work interface. The study can provide useful indications for a better understanding of workplace conflicts in order to set up the most appropriate actions to manage and prevent them.

Stress and sleep in nurses employed in "3 × 8" and "2 × 12" fast rotating shift schedules.

We compared two "3 × 8" shift rotas with backward rotation and quick return (morning and night shift in the same day) in a 5- or 6-day shift cycle, and a "2 × 12" shift rota with forward rotation in a 5-d shift cycle. A total of 294 nurses (72.6% women, mean age 33.8) were examined in a survey on work-related stress, including the Standard Shiftwork Index. Ten nurses per each shift roster recorded their activity and rest periods by actigraphy, rated sleepiness and sleep quality, and collected salivary cortisol throughout the whole shift cycle. Nurses engaged in the "2 × 12" rota showed lower levels of sleep disturbances and, according to actigraphy, sleep duration was more balanced and less fragmented than in the "3 × 8" rosters. The counter-clockwise shift rotation and quick return of "3 × 8" schedules reduce possibility of sleep and recovery. The insertion of a morning shift before the day with quick return increases night sleep by about 1 h. Nurses who take a nap during the night shift require 40% less sleep in the morning after. The "2 × 12" clockwise roster, in spite of 50% increased length of shift, allows a better recovery and more satisfying leisure times, thanks to longer intervals between work periods. Sleepiness increased more during the night than day shifts in all rosters, but without significant difference between 8-h and 12-h rosters. However, the significantly higher level at the start of the night shift in the "3 × 8" rotas points out that the fast backward rotation with quick return puts the subjects in less efficient operational conditions. Some personal characteristics, such as morningness, lability to overcome drowsiness, flexibility of sleeping habits and age were significantly associated to sleep disturbances in nurses engaged in the "3 × 8" rotas, but not in the "2 × 12" schedule.

[Mobbing and its effects on health. the experience of the "Clinica del Lavoro Luigi Devoto" in Milan]. / Le caratteristiche del mobbing ed i suoi effetti sulla salute. L'esperienza della "Clinica del Lavoro luigi Devoto" di Milano.

BACKGROUND: There is increasing interest in research, prevention and management of mobbing in the field of occupational psychosocial risks. OBJECTIVES: To describe mobbing and its health effects by analysis of the cases examined from 1997 to 2003 at the Department of Occupational Health "Clinica del Lavoro Luigi Devoto" in Milan. METHODS: A total of 226 clinical records of patients who reported a mobbing situation when undergoing medical examination were selected out of 2455 patients examined for stress-related disorders. RESULTS: The percentage of women was higher (53.1%) than in men (46.9%) with a prevalent age range of 35-54 years. There was a great variety of jobs, especially white-collars and workers in large service companies. In one third of the cases, mobbing occurred within 4 years from beginning of employment and mostly after company reorganization and management changes. The most frequent negative acts included social isolation and demotion. The most frequent symptoms were exhaustion, sleep, mood and sexual disorders. The number of symptoms was not related to the duration of mobbing but to the number and frequency of negative actions. 61.1% of the subjects took psychotropic drugs. Occupational health physicians play an essential role in primary prevention (information on occupational risks) and in early diagnosis and rehabilitation and could act as mediators between workers and enterprises.
