As long as your beliefs are "sincerely held," Title VII offers you protection no matter what your religion is. So, your employer cannot treat you differently or harass you because of your religious practices or beliefs (or because you don't have any religious beliefs). Your employer also can't force you to take part in religious activities in the workplace, whether those activities are part of a traditional religion like Buddhism, Islam, or Christianity, or if the employer is part of a newly created religion like "Onionhead" (seriously, it happened). Title VII also gives you the right to ask for accommodations for your religious beliefs if you need them to do your job.
