At-will employment exceptions checklist for Wisconsin employers
A simple order of work, based on the rules above. It is not a legal checklist.
- Say in your handbook and offer letters that employment is at will, and avoid promises of job security.
- Make sure handbook wording does not create a contract (add a clear disclaimer).
- Never fire someone for refusing to break the law, reporting wrongdoing, or using a legal right.
- Write down the real, lawful reason for each firing.
- Check federal and state anti-discrimination and leave laws before you act.
- Pay final wages on time; see our final paycheck guide for your state.
