In Cherfi v G4S Security Services Ltd, the EAT held that G4S’s request to a Muslim security guard to man a site throughout Friday lunchtimes when he wished to attend his Mosque was, in the circumstances, objectively justifiable. G4S had offered to change Mr Cherfi’s working pattern to Monday to Thursday with the option to work Saturday or Sunday, which he had refused, and there was a prayer room available on site. The EAT upheld the tribunal’s finding that the requirement to be on site at Friday lunchtimes was objectively justifiable, noting that whilst G4S had not relied on cost considerations alone, cost by itself might justify a provision, criterion or practice which is indirectly discriminatory if it satisfied the proportionality test.
