Can someone please help me in finding out the accurate answer from the following question.
The union strategy which probably outcomes the maximum wages for both the union members and other workers over long run is: (1) Limiting entry from specific occupations. (2) Lobbying for the tariffs against imports which compete with the union-produced goods. (3) Setting rigid rules for the firms utilizing union workers to maximize the feather bedding. (4) Facilitating management plans to raise the productivity. (5) Demanding consistent wage rates with premiums for the seniority.
