I received discharge letter for failing to report at my start time as instructed. I have been on disability and was under doctor's care on that day. I was tentatively released to go back to work the previous day, but was in too much pain to go. Called manager after pain meds wore off to tell him I had an appt. the next day, took him doctor note after appt. They are that I have not been communicating with them on a regular basis. I have not had local yet but business agent is saying they want me fired. Have not from doctor explaining the tentative release to work, because they are saying I should have been at work. Opinions.
