Missouri will become the 28th state to have a right-to-work law after its General Assembly passed a bill to enact it. Gov. Eric Greitens, a Republican who supported right-to-work during his 2016 election campaign, is expected to sign the bill.

That will make Missouri the fourth state to adopt a right-to-work law since Michigan did so at the end of 2012. The other three states were Wisconsin (2015), West Virginia (2016) and Kentucky (2017).
