Work in a factory in a pretty rural southern small town. We cuss a LOT. We have a new boss who has made it a rule that we are no longer allowed to swear. I didn't see anything in the employee handbook about cursing exactly. The closest thing was “offensive language”. I've been there from the start (~8 months) and no one has EVER said we couldn't and I spoke to the leaving boss who said he never cared either. We don't have any customers as it's a factory and it's an overnight shift so there are about 20 of us in the building during our shift. Does anyone have insight on if the new boss has legal right to take any course of action against an employee?
