Ok another one, this work work related.
I called in sick two weeks ago due to a work injury. However, the guy I spoke to didn't pass the message on to the duty manager so it went down as an unauthorised absence. The very next day, I had a chat to the manager and cleared it up.
Got a letter from HR about a meeting regarding this unauthorised absence. Told my manager, he said he'll have a chat to HR and that I don't need to go to this meeting. So today I got another letter asking me to come in for a disciplinary meeting, I'm guessing my manager never talked to HR about this.
What actions can I take? None of it has been my fault from start to beginning, it's just certain people failing to do their job. I'm not part of a union but if they give me a disciplinary, what can I do to take it further?
