You're not wrong...
I work in a global organisation - one of my colleagues is at a rough guess, mid 30s and the other is mid to late 20s. The latter is ok and seems to do her work fairly well but is a bit flakey.
At a recent work social event when we had new starters/joiners join us, she flicked her hair and said I'll be telling them "I'm X person, I know it all etc, follow me!" yet on the day she was anything but this person she wanted to portray!
I was told by the mid 30s colleague that the other colleague was 'unreliable' when I helped her out. And then today when I was off sick (I'm a contractor, temp) both colleagues refused or couldn't help me, zero effort.
I'm not sure if the younger colleague makes a lot of mistakes, as I don't think she'd be in her job if she did this!
The interesting thing is:
- a colleague who's a similar age to me - in her 40s recently left our organisation after 10 months, this colleague has won awards for being a PA, she was also covering maternity leave as well as doing her job.
- another colleague in her 40s or my age (51) has been there 5 years and 1 year as a PA and recently left.
I'm not sure and wouldn't ask if they were both fed up of the Gen Z's not pulling their weight etc.
I'm the sort of person who always offers to help out, if I have capacity, because that's the type of person I am. I've also worked as a legal sec for almost 10 years and they never have a quiet moment (constant work) so I know about job pressure!
We do however have a few graduates/new starters who are young or apprentices and although there are teething problems with them not attending college etc, we take this on board and cut them some slack. You couldn't be totally callous and not understand their issues, especially after Covid and lockdowns etc.
