I share an office with a new-ish (since last 2022) colleague. We exchanged personal mobile numbers so we could coordinate days in the office.
Since starting, this colleague has been quite a handful. She's had on-going gripes with our line manager which she was talking about escalating to the union (not sure if she did). For what its worth I think her gripes are unfounded.
Anyway, she's messaged me a few times on my personal mobile number to ask work-related questions, always questions about the on-going gripes she has rather than more general procedural/admin stuff IYSWIM.
This weekend just gone, she messaged me asking me to become her mentor. It's pissed me off for several reasons - messaging work-related stuff to my personal mobile, on the weekend, asking me to take on additional work and to walk into a shit storm of grievances.
I've drafted a response a few times and then given up.
DP has said that I should just ignore the message and wait for her to contact me through official channels (work email) given its official work business. I'm coming around to this way of thinking but not sure.
So, WIBU to just ignore the message as DP has suggested?
For context, it'll potentially be months before I see this colleague face-to-face.
I'm reluctant to email and say "Don't message my personal mobile" because this colleague already feels that everyone's against her at work and I don't want my name dragged into that conversation (even though I absolutely know I'd be reasonable to tell her this).
