Called off work yesterday and told first shift I wasn’t going in and he said ok well guess he never told second cause she called me saying it’s a no call no show like no and my sister answered the phone acting stupid answer it with information she didn’t know. I have a doctors not saying I won’t return till today. So if I get a write up I’m going to print out my cal circle that I talked to someone and turns that in with the note. Since we aren’t allowed to text to call off
