Block their personal number. I totally disagree anyone texting or calling when the person is not on the clock. If the issue is so dire that only you can address it, you are not making enough money. This seems to be more and more accepted. Working off the clock can be grounds for termination. This can be overlooked until they need/want to play gotcha! Anytime they call or text do a punch correction. When HR is realizing that you are having 20-30 punch corrections in a week, it will stop. Work email is for communication. There are reasons you cannot access it from home,one of them working off the clock. Block, Block Block
