Of course it is. It won't pass. Millions of gov employees at all levels are unionized. They won't tolerate random testing BS. As well as all those creating the laws and those judging others won't tolerate it either.
It's like Congress opting out of Obama Care, but creating law and rules forcing others to obey or else.
Wisconsin’s state employees are no longer unionized.
I also found this article about Portland’s police adopting random drug testing.

“Major metropolitan police agencies across the country including Los Angeles, New York, Boston and Milwaukee, Wis., have adopted random drug testing. The FBI does random drug testing of agents.”
An interesting article about when city governments can drug test employees. It does not violate the 4th amendment. It’s a good read and it mentions truck drivers, school bus drivers, etc. that can be randomly drug tested. The key word is “random”.

Here is the link to the PDF file that is the Drug testing policy for the Milwaukee Police Dept. It covers all of the instances where drug testing is required (even when they are promoted or have been on an extended leave) and also cover random testing. The chief determines the frequency and officers are chosen randomly.

The officer I spoke with on the phone was kind enough to email the link just for you:) A simple thank you will suffice:)
