I used to have the same problem. Then I learned to say "NO" . Your health and sanity are not worth the money, and honestly does not endear you to your employer. I know the guilt you are feeling from saying no but you have to put you first. If you stop answering or say NO a few times, the number of calls will decrease. It is your life outside of work. After 16 years on the job, I have learned you have to take it. Saying No does not make you a bad person or lazy. Don't answer the phone if it is work unless you want to, they can leave a message and you can return their call at YOUR convenience. Don't let your work become your life or it can prevent you from having one outside of your work. I found it alot easier to say NO after I fell in love and wanted to spend my days off with this wonderful man. And after we got married, it got easier, because my job was not my life but my home life was.
