Everyone's superstition is wrong to the other guy.
Many Jewish districts and businesses with large Jewish workforces have Jewish holidays for workers. Jews aren't very numerous. What's wrong with it though? Why shouldn't a plant with a lot of Chinese or Muslims give them the option of celebrating their holidays. It's just good labor releations.
