not everywhere.
will you deposit your money to bank clerk, that was in newspaper as suspect in fraud?
there are number of jobs, that you have to be clean, and once you are suspect... you are having long vacation (without pay) until you come clean.
I have seen friends being let go because police investigation (no pay no severance), but if you are member of union, that's different story.
This has nothing to do with a union. These types of protections are in place to protect polce officers from false accusations from the general public. If they lost pay everytime they were being looked into they would never get paid. Unfortunately these same safe guards also protect the bad apples when they do bad things.
I do not disagree with them being off with pay, but if convicted I think they should have to pay it all back.
