I have NC for this as it's kind of sensitive.
My boss is really nice. We're not friends exactly - she keeps a professional distance, which seems sensible to me, but we do get on well and her supportive management style has done a lot for my confidence. It's the nature of my job that I sometimes work at different sites and can be offered extra shifts (which are optional but I often accept them). My boss usually lets me have my schedule for a few weeks at a time and gives me as much notice as possible if there are any changes.
Just lately I have noticed a few mistakes and miscommunications. I might already have a certain shift on my schedule and then get an email saying "sorry, we're really short-staffed - could you come to Hilltown on Thursday morning?" when that's exactly what I was originally supposed to be doing! And once it was the other way round - I hadn't been told about a shift and knew nothing about it until someone messaged to ask where I was.
I'm 100% confident my boss wouldn't be trying to gaslight or inconvenience me, so that leaves the possibility that she's not quite managing to keep all the balls in the air. I don't know for sure that nobody else has noticed, but nobody has brought it up in my hearing, and the only time I ever light-heartedly mentioned one incident to a colleague, they just said "well, she's busy" But she's always been busy. She's about 60, a bit young for dementia to be likely.
Part of me thinks I should flag this up to her boss, as a concern about her welfare rather than a complaint. But I don't know her boss very well (we never work in the same physical location) and it would also be very important to me that my boss never realised it was me that said something. We have such a great working relationship, I'd be sorry to lose it. So basically my question is WWYD?
