"Civil service protections
The protections are put into state law by the Legislature, or into a local ordinance by a city council, or village or town board, said public-sector employer attorney Andrew Phillips. He is general counsel for the Wisconsin Counties Association and his Mequon firm also represents municipalities and school districts.
Currently, state employees are covered by civil service, but most local government employees don’t have it and no public school employees do, Phillips said.
Phillips said civil service protections, among other things, specify employee rights to things such as vacation and overtime; prohibit termination for reasons other than just cause; and create procedures for employees to file grievances and to have those complaints heard.
What they don’t provide, he said, is any right for employees to bargain with their employers over those issues and others. The terms are set by the employer.
Collective bargaining rights
Two sections of state law -- one for state workers and one for local government and public school employees -- give public employees the right in Wisconsin to collectively bargain.
The law issues a mandate to both the employer (the government) and the collective bargaining unit (employees represented by a union).
The two sides must "meet and confer at reasonable times, in good faith, with the intention of reaching an agreement" on wages, hours, fringe benefits and conditions of employment.
In other words, the workers -- through their union -- have a say in those areas. They do not have such a say under civil service rules.
So, what would change if Walker’s budget-repair bill is adopted by the Republican-controlled Legislature?
With an amendment approved by the Joint Finance Committee, the bill would require local governments that don’t have a civil service system to establish one, according to an analysis by the nonpartisan Legislative Fiscal Bureau.
Alternatively, local governments could establish a grievance procedure that would, at minimum, address employee discipline and workplace safety, and provide for a grievance procedure for employee terminations."
It's not exactly crystal clear - is it?
