Firstly, one of my favorite application & interview questions is -
Is there any reason you could not perform all the duties required for this job?
This has weeded out vegan childminder who would not prepare meat, a person who did not want to miss the 5:09 train (because husband didn’t want her to be late for dinner), a person who would not have client meetings with pharmaceutical companies because of her views etc
You would not need to have said this job requires you to meet with men, but if she cannot meet with men, then you could have not offered or if she took job, then stated it, then you have it in her application.
Given that she had not mentioned it, then confirm with her via email. Dear X, just confirming that you are not able to attend ABC meeting insert her exact words about men but not religion. Let her respond with that.
Each time there is a meeting in future, ask her to attend as you would anyone (in writing) so you have her responses in writing.
It might be that over time, she contributes as much as peers. But if she doesn’t, and she complains, you can say.
Ms T, your peer, has been able to attend & close 26 client meetings this year contributing ££££
You have been able to attend and close 7. Contributing £
Ms T is getting promoted to recognize her contribution to expanding business etc
Another view, which I cannot help but raise, is that there are men that she is discriminating against as well. Like if she won’t meet with an internal colleague …
They can claim discrimination against her.
My best advice is follow up every conversation with carefully worded email & keep.
Time will sort this out, the longer you wait, the more evidence you have that you treated her fairly and she fails to meet performance of others by her not accepting male colleagues.
As a company, your goal is to say, we treated her fairly, invited her & she declined. We cannot tell clients to exclude men as that is illegal. She has had every opportunity but turned down meetings.
