This would be tricky for very small businesses, but for everyone else, why is it not regular practice to have a separate page of the application form with personal details on which is then detached (as an equal opps form often is)? Bit of a TAAT but why is a system accepted that means employers will often discriminate against those which are 'unusual' (inviting class judgements), Muslim, or even female? Obviously there could still be discrimination at interview but that first hurdle is so important.
