Employees at Pabst Brewing Co. are no longer allowed to drink on the job.

In a new contract approved this weekend, Pabst machinists agreed to give up the free beer they have been getting for years during breaks and lunches, Pabst spokesman Bob Milkovich said Monday.The change will affect all employees in the plant, including both hourly and salaried workers, Milkovich said.

Pabst employees, however, will get two free cases of beer each month starting in December as part of their compensation, a practice followed at other breweries.
