This from ACAS: //In some limited circumstances, indirect discrimination may be justified if it is necessary for the business to work. For example an employer may not employ someone who insists on having certain times off for religious observance, when the time they want off is the employer's busiest time, and all staff are needed to ensure customers' orders are met.//
And before anyone repeats that the link in the OP is an old one, I know. Just clarifying the question of employment law that’s been raised.
