Help! I left our plasterer to skim over our lounge ceiling today whilst I was at work and he has chipped off large chunks of it, left it all over the floor and then skimmed the ceiling. This is AFTER I told him it had white asbestos in it! He then SWEPT up the debris and chucked the stuff in the nearby bin. Surely this is all highly illegal because he's not asbestos licensed and he shouldn't have put asbestos in the regular bin?! What should I do?
