So my boss put in our work contracts that we’re required to work certain events during the year, including holiday parties that my religion prevents me from participating in (Easter and Halloween). She just sent out an update saying the Easter and Halloween parties will now be called Spring Fest and Fall fest. I’m sure she did that given our recent conversation about how I would/could not participate for religious reasons. The basis of the party is the same (to celebrate the holiday). Can she force me to work them or can I still use the fact that it goes against my religion?
