long series of cases at the Employment tribunal that contracts whcih say this is not an employment contract is determined to be ..... an employment contract.
leading case is this I think
https://en.wikipedia.org/wiki/Ready_Mixed_Concrete_(South_East)_Ltd_v_Minister_of_Pensions_and_National_Insurance
a bit like Street v Mountford for leases.
( licences saying this is not a lease are construed as .... leases)
usually the reader will be glad to hear
a contract is a contract is a contract.....
