The essay analyzes job rules with regard to what has been cal-led the «little Privatization», that is the transformation of munici-pal firms in companies. It particularly concerns the modifications of art. 2112 of Civil Code — the general rule in this subject — by art. 62 d. lgs. n. 29 of 1993, through which the privatization of the whole Italian publíc employment has been carried out. This law has widened the legal notion of «firm sale» for the public sector, but it hasn't given stronger guarantees to the employees' acquired rights. From this point of view collective bargaining plays a very important role. Therefore the Author examines Trade Unions' in-formation and consultation rights, granted for the «firm sale» by rules originated from the European Economic Community, and points out that in these cases they are not always adequate to en-force rules that have been thought for the industrial sector.
