Possible attendance write-up

I'm confused, you missed a class they didn't tell you that you where in, and now if you're late for work or have to call out then you're fired?

Essentially, yes. I have emailed my supervisor to explain what happened but she hasn't responded to me (but she has sent out other emails in the meantime to our unit as a whole).

Are you unionized?

I would absolutely make sure that a confirmation email isn't in a junk or trash folder. Do you have an online learning center? Any class we register for shows up there and that is our confirmation. Then I would contact education and training and tell them what happened and see if they can figure it out on their end. I would then GO to the UM, not an email and explain what happened. You can also write a rebuttal on the write up that goes back to HR.

Not unionized. And I do plan on going to my UM, but she is leaving for vacation.

I have checked all my emails. I received an email for registration without a date or time since I was on the wait list for the class, but nothing else.

Also of note we have a brand new online system for classes

OP had apparently accumulated enough prior points for calling out/being late that the points for the "no call no show" on the class day triggered some corrective action.

Yes, I had previously acquired enough points that missing this class would put me into corrective action

Not to be pessimistic but you are on the best way of getting fired.

can you call her?

I'm curious how many of these points you can get before they case warnings and write ups. Do they start falling off gradually, or will nothing happen at all until 6 months and then they're all gone? 6 months is a long time to have nothing happen. Is there anything you might qualify for FMLA for?

I did get in contact with my manager, and she told me not to worry about the class since the new system has some glitches.

The points fall off one year from the date they occurred, so I have several falling off but if the no show for ther class would have counted then I would have been in disciplinary action and therefore none would fall off and I would have to go 6 months with no occurrences whatsoever or face immediate termination.

Honestly I would start looking for a new job. These punitive systems encourage nurses to work sick -- what if you had influenza or norovirus? Or what if you had a small, sick child -- sick children can't go to daycare. They're penalizing a call out for those, as if you had called off to go to a party or something? I would not want to choose between working with influenza or getting fired for not working with influenza.

In the meantime, can you screenshot your inbox to show you had no notification? (The IT people should be able to tell if you deleted it and lied about it, in case they accuse you of simply deleting a notification.)
