Please don't tell your Jewish coworkers that they're making it difficult for you by missing work. I promise it is out of our control and we are constantly made to feel selfish for doing so. Provide Jewish people the accommodations they may ask for whether that be rescheduling something or helping them to find someone to cover their shift.

Additionally, a Jewish person's level of observance is none of your business. Some may take the day to spend with friends and family and some may spend the day at their synagogue. Some may fast on Yom Kippur and some may not. Some may continue to go about their lives as usual. None of these make a person any more or less Jewish and it's not your place to comment on.
