As soon as I changed it, I told management that I no longer wanted to be contacted through any method other than email. They don't pay for my phone and therefore don't get to dictate when and how they can contact me. A couple of the managers were obviously upset and asked directly why I didn't want work to have my number. I told them I am there for a paycheck and not friendship and I don't want to be contacted by any of them on personal time.
