I normally avoid getting involved in this specific conversation, however, I have something to add, which might throw another direction of thought.
I was engaged as a Contractor, to a very larger American Corporation in the UK, through an agency, on an Employed Consultant basis. After I had been there two years, I was informed that I was entitled to 33 days full pay for holidays, plus 10 days sick pay. Prior to that I got 26 days fully paid holidays. Effectively a zero days contract, PAYE, but at Contractor's rates.
Room for thought?
