having weekends and child labour laws?
Careful with this one, as it can open the door to questions as to what Unions have done for non-members in the last 50 years.
Unions are great - my day job is union I.T and so was my last - but I'm only keenly aware of how a dear friend fought his dismissal on grounds that were so bad it was a human rights / disabilities case, and after a blazing victory he won ... severance. It'd be neat-o if our unions could remember who else lives in this country and fight for rights outside their little club.
