Some time ago, I set up an agency organising lingerie girls to come to work in a pub. As such, I invoiced the pub management each week for the girl supplied and paid the girl, taking a small percentage as an agency fee. Recently new management have taken over the pub and they have decided not to use my services. I have just discovered they are contacting the girls I spent a lot of time booking, attracting and organising to work at the pub to come and work directly for them or for them through another agency. I spent a lot of time and efforrt finding girls and persuading them to work at the pub. I feel that I should invoice the pub every time they use one of the girls I found and contracted. Where do I stand legally on this under Commercial Law?
