My work deals with the family theory, history of its...

Further on I describe particular roles within which a social worker can have a positive impact on employees whose work performance is dropping due to the negative influence of their personal problems. Apart from work with individual employees, a social worker can focus also on improving social climate of the whole enterprise.
