A bit of a follow up to Should I follow up with things that aren't my fault, or forget them? Example: was told I was late for shift I didn't know about
Where I work we become union after 250 hours, and effectively that is also the end of the probationary period. At work today I asked a manager how many hours I had eccumulated. She said about 100 but management needs to have a talk with me when I get close to 250 because there's been some concerns. I asked what type of concerns and she said I did not show up for a shift the other day (see linked questions). I told her that I wasn't informed I had one and had checked my call history for the day prior to the shift. She said she thought she had called me on another day, other than the one the day prior. Should I follow up further? I got the sense there were more "concerns" than just this one thing, though I may be paranoid.
Would it be reasonably for me to suggest having the discussion sooner so that any issues can be corrected? Should I schedule a meeting with management or just ask if there's any concerns next time I see them and they don't look too busy? I feel like I'm doing well in this job but also noticed I haven't been getting much feedback.
