WAUSAU, Wis. (WSAU) – Wausau police officers will give up their pay raises until the end of 2010.

The police union agreed to the concessions Tuesday in a last-minute effort to help the city overcome a nearly a half-million dollar budget deficit. The union made the concessions with the hope that they would prevent layoffs in the department.

The police union is the second of five unions to make concessions.

Late last week, the city's firefighters union agreed to wage cuts in 2010 and to leave open two vacant positions.

There has been no word from the three other unions representing transit, clerical and public works employees.

Clerical and public works staff will take the first of two unpaid furlough days Wednesday. The public works union lost 10 of its members to indefinite layoffs last week.
