The Occupational Health Care Act obliges the employer to provide preventive occupational health care services to the staff when there are one or more employees, regardless of working hours or duration of employment. The occupational health care provided by the employer is divided into statutory preventive occupational health care and voluntary supplementary occupational health care. Organizing nursing care is voluntary. When purchasing occupational health care services and planning and assessing operations, the law requires the matter to be handled together with the staff or their representatives. Depending on the size of the workplace, the discussion is held in the work safety committee or with the health and safety representative or the entire staff. Preventive occupational health care includes: 1) workplace survey designed to identify the effects of the work, workplace and work environment on health and working capacity, 2) physical examinations based on health risks, 3) participating in activities that promote working capacity, 4) guidance for workplace emergency preparedness, 5) monitoring of employee health, rehabilitation counselling and referral to rehabilitation when working capacity declines.
