Integrated worksite health promotion takes into account as well the demands of employees as those of the enterprises and at the same time applies to both, health behaviour and operational conditions of the companies. It is not restricted to a singular action but makes a continuous effort to promote the health of employees as an integrated part of employers' planning and politics. Apprehension between employers and employees seems to be one of the key obstacles of worksite health promotion. Therefore both sides have to keep negotiating to what extent health promotion has to improve efficiency of employees in respect to enterprises or how far operational conditions have to be adjusted to suit the well-being of personnel. A possible solution to solve this dilemma would be a widening of the conception of efficiency and incorporating of long-term thinking.
