Is your continued mask use your own choice or are they still required in your town?
In Oct. my workplace instituted mandatory vaccination if one wishes to remain employed. There are two exceptions, confirmed medical excuse and religious belief. I have not gotten a firm answer on why religion is given deference and it seems difficult to justify. It must be a very common practice though as there are web sites that list out bible verses and their interpretation so anyone can quickly have a religious exemption. I do not know what allowances are made for other religions.
I was told by one of the clergy at work the religious exemption is very easy to get and there are ordained pastors doing online business selling people documentation for religious exemption which the pastor has signed. Guess the signature gives the document more acceptance.
