I started a job two weeks ago and the3 second week I got strep throat and was told to take the week off with a doctors note to prove it, I called the super and told him what was going on and he said to come back when I was able too, then two days later I heard from a fellow crew member the super was mad at me for not calling in everyday, even though I was specifically told I did not have to, so I started calling in everyday after that, and now I hear I may be getting fired because of it, is this possible in a non union job?
