My employer is concerned about cell phone usage during work hours, because some people made inappropriate calls or played games instead of working. Now we have to have our cell phone silenced and put away during our shifts, in a drawer or purse, and not out in the open. All calls to us during work hours have to come in through the work number.
I have a medical issue, and don't want my employer to know the details. My employer will let me get calls at work for a medical issue, but I don't want them taking messages for me and I might not be available if they try to transfer a call. Do I have the right to use my cell phone?
