Right so you are trying to provide a defence to discrimination by a supplier on the basis of a protected characteristic?
You know, right, that fringe employees during the festival tend to be on temporary contracts and don't tend to be able to control their employers to the extent you seem to think they can? I mean golly if employees had such control why have teacher and nurses held the govt to ransom over wages?
This employer cannot defend on the basis you seem to think it can, even if it could prove that the temporary staff it engages exercise such control.
Lack of defence funds are no defence to discrimination. How strange that you think it is?
Interesting that you have failed to answer whether you think that lesbians who don't do dick are the bigots. I think you do.
