Is this discrimination?

[Nacknick]

I have a chronic health condition recognised under the equality act. My boss has arranged the team Christmas lunch in a location that I cannot access due to travel restrictions placed on me by HR following an occupational health assessment.
Is this discrimination?

It's definitely discrimination. The words festive and goodwill do not spring to mind.

I'd start off by saying how disappointed you are that you can't attend and take it from there.

If you are unable to attend the Xmas party, why don't you ask for something in return. Some companies allow staff a set amount to be spent on food/meal and you claim the money back on expenses. Or ask for some time that is paid off work. However, the lack of invite is still unfair.

I don't think you need to approach your boss at all. I would suggest speaking with HR, advising you are being discriminated against as a result of your disability and while your boss may not have thought of you when selecting the venue, they should be made aware of the fact that their thoughtlessness is part of the whole problem.

HR should offer guidance on how to manage where employees have various disabilities to ensure they are fully engaged/considered and I see this conversation as falling within their remit. It doesn't have to be that you have complained about your boss.

In the same way when I was discriminated against while pregnant, I felt able to raise it with my boss (who had the best intentions but illegal essentially) but if I couldn't I would have asked HR to speak to them under the guise of education rather than reprimanding.

Sorry that is so waffley!
