I signed up for your job in a certain location and a certain date. That doesn't entitle you to keep track of where I am the rest of my life. As long as I'm able to be reached at the initially agreed upon location, regardless of how I maintain that communications channel, I never agreed to let you dictate where I live and move to and frankly nobody has that right.
Or is my body my choice just a convenient catchphrase for one topic only?
