Your post is bizarre.
Whats Boris for to do with anything? Is Ops colleague Liz Truss?
How the colleagues kids might feel in the future, isn’t Ops business.
if a poster posted about her husband lying, that would be a personal issue that impacted the op directly. I would say the colleagues were weird, for asking their dh to sack them, if they also admitted it had no impact on his work.
The op isn’t impacted directly because they are colleagues. The colleague isn’t lying about Op. It doesnt directly impact op, other than she is choosing to get involved.
No one said having friends in HR doesn’t help people. But it’s really odd, to lie about your marriage when your best friend works in HR. It’s really odd to go to Hr knowing they are best friends and asking HR to sack someone. You have no right to tell HR to sack someone. You can take a problem to them, but your opinion on how it should be dealt isn’t part of that.
The ops behaviour is so odd, that I believe she has something incorrect. She has crossed wires somewhere. The colleague can’t be sacked. And the Op should stop investigating her personal life. If it impacts the work, then she can take that back to HR.
