Frequently Asked Questions

What if my coworkers complain about my accommodation?

Coworker preference or discomfort is not undue hardship. Employer must accommodate unless substantial burden on operations.

Can I proselytize at work?

Limited. You have right to practice religion, but employer can restrict proselytizing that creates hostile environment for others.

What if I need multiple religious days off?

Employer must attempt accommodation. May include combination of paid time off, unpaid leave, schedule adjustments, shift swaps.
