I don't care - i'm just doing what everyone else is doing and stating my opinion on a post on the internet. Why does that bother you?
I never said anyone shouldn't work from home, please explain where I have said that.
What's entitled is the attitude that people should do "what's best for their personal circumstances" - well yes they should in general, we all need to look out for ourselves but that doesn't extend having the right to do your own thing when your employer has clearly asked you to come into the office once a month.
If OP had been asked to do it once a week I'd side with her, but once a month is reasonable and they said they'd be happy to settle with that.
The employer is the one that pays your wages so you can live this life of "what's best for your personal situation" just in case you thought the money fell out of the sky.
As for WFH being a productivity issue - my attitude is that it can be depending on the person, some people are good at home, some are not but at the end of the day there isn't a substitute for simply being a normal human being and seeing your colleagues like we did pre-pandemic which was apparently 100BC according to most people these days who have built their lives on the assumption that being anti-social to their employer is going to be seen as the new norm.
Working at home is a flexibility granted at the discretion of the employer, not a human right as many people seem to think it is. Seeing your colleagues does make a difference actually.
There's also the fact that from her employers POV if they don't like her rigid attitude of refusing to go into the office, it is easy to start excluding her from things that are only discussed in the office, which is fine if that's what OP wants - it's an easy way to get managed out and for what? The insistence that the her right to not do the same as everyone else comes before everything else.
Good luck with that attitude.
