According to research findings, public officials have sufficient knowledge about union regulation but they think unions barely perform the activities forecasted in law no. 4688. Public officials stated that unions express their opinions related with the melioration of working conditions, fulfill the legislative assistance demands and take care of the problems about work and work place.
