People should have the right to practice their own religion/beliefs regardless of whether other people consider it to be sincerely held or not. However, that doesn't mean that they have to follow the requirements themselves. If a religion prevents a person from working on specific days, then that person shouldn't be forced to work on those days, but similarly, a workplace shouldn't be forced to employ them if they can't arrange a suitable compromise (e.g. they don't work Saturdays, but they can cover all the Sundays).
