This essay analyses the nature and the extension of the powers assigned to public management by the public employment reform act of 1993 (d. lgs. 29/ 1993). Aim of the article ís to evaluate the relationships between the exercise of the new public management powers, the unions participation rights and collecti-ve bargaining.
In particular, the essay scrutinizes the «negotiability» of public managementpowers, that is the possibility to make them object of collective bargaining with unions.
Having examined the different interpretation offered by scholars, the Author proposes her own solution, which excludes the possibility to bargain with unions prerogatives that the law has specifically reserved to the competence of public managers.
