Background: started new job in July 2020, promotion, in NHS, new team. Two other new starters in my team (started before me, April 2020) are the same band. I work closely with them (their job 'feeds' my job) but have only met them face to face once as neither of them have been keen to come into the office (I had to be in the hospital, they could wfh).
Fast forward to now, one of them had her probation extended in October 2020, to be reviewed in January 2021 with specific instructions on how to improve her performance. It does seem she has tried very hard but obviously I have limited knowledge. We only know this as she shared with me and other woman who does same job as her. The management gave not mentioned it at all. We were supportive and listened and I advised her to join the union back in October. She didn't. She had a meeting this week and they have said she usn't meeting job requirements and is working two bands below. They have told her to bring a union rep or a colleague to the probation review in Jan but have been clear it is very unlikely her probation will be passed.
She has asked me to attend the meeting with her. My 6 month probation meeting is the day after. My instinct is that I will be shooting myself in the foot advocating for her. She said in her message asking me 'Will you be my representative, as in help take my side'. For more info she is 25 weeks pregnant and english is her second language. AIBU to say no? I had told her to join the union! I feel if I say yes, she will expect me to basically act like her lawyer and there is no way I can as I don't know all the information and I don't want to paint myself into a corner. Her managers are my managers. My instinct is to 'help' but my experience has taught me not to do that to my own detriment and I suspect she wants more 'help' than I actually can give. AIBU?
