means that: • the risk was previously unknown and is caused by new processes, new technologies, new types of workplace, or social or organizational change; or • a long-standing issue is newly considered as a risk due to a change in social or public perceptions; or • new scientific knowledge allows a long-standing issue to be identified as a 

Study results lead to the identification of a

top of emerging psychosocial risks

as follows:  – – –

New forms of employment contracts and job insecurity

new forms of employment and contracting practices (e.g., temporary contracts), and the trend in companies towards new forms of production (e.g., „lean production” and „outsourcing”) are important factors affecting the occupational health and safety of many workers.

Workers in these types of contracts are more vulnerable than, for instance, permanent workers, and successive short-term contracts and of the resulting discontinuity in work careers  the risk of social marginalisation.

Workers’ isolation caused by new forms of working patterns such as telework or temporary work is also put forward.

These implications, in the context of unstable labour markets, increase

workers’ feeling of job insecurity

, which augments the level of work-related stress and may have a negative impact on workers’ health.



Work intensification:

– high workload and work pressure as a consequence of the reduction of workplaces, and also of the growing amount of information to handle at work as a result of the introduction of new Information and Communication Technologies (ICT) into the workplace; – a higher workload and demand shared between fewer workers, hence an increase in work-related stress; Within this context, workers may also fear to be more assessed upon their efficiency and the outcomes of their work, and hence tend to work longer working hours in order to finish their task, sometimes without receiving adequate compensations (in the form of free-time or financial compensation) and social support. – European statistics indicate that

almost half of all European employees work at very high speed three quarters or more of the time

.



The ageing workforce:

– – – It is a consequence of both the ageing population and the higher retirement age. Ageing workers are more vulnerable to poor working conditions than young workers.

The failure in providing ageing workers with life-long learning opportunities increased mental and emotional demands upon them, which may: • • affect their health, and increase the probability of work-related accidents.

 –

High emotional demands at work:

Workers may try to hide their difficulties in coping with these demands as a reaction to the fear of losing job, which can be the source of additional stress.

– – The issue is not new, it is a growing concern, especially in the health care and the service sector, which is growing and where competition is increasing.

Workplace violence (and also esteem, anxiety, depression, „bullying”, „mobbing”) was identified as a contributing factor to this increased emotional demands. The consequences of workplace violence may appear in psychological pathology (deterioration of self apathy, irritability, memory disorders etc.), and somatic pathology as well (organic, functional and sleep disorders, alterations in the cortisol cycle, loss of appetite, hypertension, vomiting, chronic fatigue, back, muscular and joint pain as well as headaches etc.).



Poor work-life balance

– the

relevant literature

stipulates that irregular working time, especially combined with the lack of possibility for the employee to arrange thier work to a certain extent to their personal needs, often causes problems affecting the work life balance and the employees’ health. Non standard hours such as shift, weekend, and night work can be especially disruptive for work-life balance when the employee is in a precarious employment situation. Casual work combining high work intensity, variable and unpredictable working hours lead to work-life conflict and has detrimental effects on wellbeing.

Statistics

• Stress is on the second place in the top of the most frequent complaints regarding work related health problems.

• Stress affects almost one of four workers in EU.

• The studies showed that between 50% and 60% of all not performed workdays are stress related.

• The economic costs of work related stress in EU-15 was about 20 000 milions EUR in 2002.

• The number of persons affected by work related stress could grow.

Approaches

 One of the main characteristics of the new approaches in both scientific and OSH risks practical prevention fields is referring to approach of risks, taking into account that: the necessity of a multifactorial, multidimensional and, as a consequence, a multidisciplinary – Under the circumstances of new techniques and technologies, there is the danger for personnel to be exposed to

a cumulus of occupational noxes

; – One and the same risk factor, especially the neuropsychic overload and psychological stress, is a result of a cumulative action of different occupational (therefore, multidimensional), extra-occupational and individual factors; – Human being is a bio-psycho-social entity, which reacts as a whole at external / occupational factors; the reactions could be somatic, psychological, behavioral plans, depending on the nature of risk and individual vulnerabilities.

Organizational and leadership factors:

• role (task) ambiguity • conflict between work demands • responsibilities on people and their safety or, on the contrary, lack of responsibility • lack of consultation and participation in the decision process • unreasonable restrictions regarding the work behaviour • lack of control and auto-control

Interpersonal relationships:

• difficult relations with the superiors, colleagues and / or subordinates • inadequate psychosocial climate • absence of feeling of group membership • no safety feeling • lack of self – confidence • lack of appreciation, recognition and support

Workers groups most at risk

Although the majority of EU workers have typical work schedules, gender, age and socio professional differences are observed in terms of the prevalence of atypical work schedules. Some employees seem to be especially at risk because of flexible or irregular working time.

Age Older workers

(between 55 and 64) are less affected by, but not excluded from, atypical work such as night work, shift work, weekend work and irregular schedules, than the younger age groups. For instance, in 2005, about 20% of the EU25 employees in the age range 24-39 reported shift work, whereas there were 16% of such employees in the age range 40-54, and 11% among those the aged 55 and more. Nevertheless, workers aged 65 and over are well involved in atypical time schedules like weekend work, irregular schedules and other atypical schedules specific to the service sector.

Stress indicators at organizational level

• Absenteeism • High fluctuation of the work force • Disciplinary problems • Violence and bullying • Low productivity • Errors and accidents • High costs coming from compensations and medical care
