Grassed up....

You’re agency, they can decline your services anytime they like, but all companies are pc now. I suppose it’s a bit late, but all companies have a health and safety mission policy on their website and I’d throw that back at them. Whatever you do, don’t try to argue the issue with what you thought because these people will run rings around you. Throw their H&S policy back at them and put them on the defensive instead. Good luck.
