If someone doesn’t want to shake hands fine but they should apply that rule to everyone equally regardless of race, gender and religion. Otherwise it’s discrimination no matter the reason, religion is no excuse to discriminate. Especially in a professional business environment.

If it was a white Christian who doesn’t want to shake the hands of a Muslim nobody here would defend the Christian.

So if a white person doesn’t want to shake the hands of a Black person they shouldn’t be fired for discrimination?

I would have fired him as well. Even if I had to pay him out. If he refuses to shake hands with anyone that would be an entire different matter, but the don’t touch women rule some Muslims adhere to is rooted in sexism and misogyny.

Any mid to large size company has the USB ports of their desktop PCs disabled, disconnected or even glued shut. At least the ones that take security seriously.
