ali23 what a horrible situation.
Firstly your options.
- If they want to withdraw your flexible working arrangement this is a change to your existing terms and conditions so they need your consent to do so. You can refuse consent to this change and continue to work from home as you have been.
If you do this they might attempt to discipline you. You could then appeal any disciplinary action, and could take it further if need be.
Benefits to this are that HR would have to become involved if they want to discipline you, and from your point of view I'd say that's a good thing.
Downsides are as you have mentioned.
- You could put in a formal flexible working request. They would not be able to turn this down reasonably as the arrangement has been successfully in place for several months.
Benefits are again HR would probably then have to be involved, downsides are the same as above.
- You could attempt to deal with it yourself. Try to ascertain exactly what the problem is with you being at home, and try to address it.
Benefits - you won't get people's backs up as much by the sound of things.
Downside - it doesn't sound very likely to work, although might be worth a try first anyway.
- Look for another job. I don't know what you do obviously or what else it out there, but worth considering at least longer-term.
Benefits - you would hopefully end up in a better environment.
Downsides - you may not be able to work one day from home initially, although I get the impression you are working full time, which will be easier to find than part time probably.
- You could raise a grievance about this situation. It sounds like bullying, potential sex discrimination and an attempt to deny you your statutory rights.
Benefits - again, it would get HR involved, it would mean you had 'ticked the box' of bringing an internal grievance which you must do first if you end up bringing a tribunal claim, and it might get some of these issues addressed, for you and for others going forward as well.
Downsides, as you've mentioned. You would quite possibly be burning your bridges.
I can't tell you what to do. But those are some things to consider. I think you should think about what you want to achieve. What realistic outcome would you like from this less-than-ideal situation? Think about that then think about the best thing you can do to achieve it.
Good luck. Do come back if you have any questions about any of those options or anything else. I'm sure others will come along with their experiences which might give you a bit of an insight into your options as well.
