Discussion on question by Duzii2: My manager warned me about absences on short notice

@Duzii2 I'm not impressed with you attitude. Reading your post and comments from this and other questions it seems you blame everyone and everything instead of trying to figure out what you can do to improve. Normally it's not important who is right and who is wrong, the important thing is that everyone improves. Your way of blaming everyone and everything else will rub people the wrong way, and you are the one that will suffer from it. Here people are using their free time to try to help you, and you clearly don't want the help. Why are you asking for help if you don't want it?

@Aserre, they wouldn't be fired for a health condition, they would be fired for not communicating about missed time. OP found out about the appointment on Friday but didn't inform management until during the day Monday. They missed a client meeting without ample notice, that is a problem especially if repeated

why didn't you tell your manager about the doctor's appointment on Friday when you found out about it, and instead waited until Monday before telling them?

You joined the company recently and this have happened 3 times? You got info about an appointment on Friday and waited until Monday to tell your boss? The doctors appointment was in the morning, and you got sent on, resulting in you missing work in the afternoon as well? You need to get on top of things and start communicating. Life happens and you of course need to go to doctors appointments sometimes. But you also need to make sure your employer knows when you will not be working, to allow them to plan things. They could have rescheduled meetings if they knew about your absence.
