Re: @Herring: Just a question
The ironic bit, which I forgot to add was: if you were contracting for HMRC. If they deem you to be an employee for tax purposes then you demand to be an employee for all purposes.
If they were to try to push for all contractors to be inside IR35, then it would do a lot of damage to the sector. Either rates would have to rise sharply or many (including me) would look at going back to permanent work. Probably a mixture of the two.
Contract rates may seem like a lot of money, but the client is saving on all that HR bullshit that comes with employing someone. If rates did rise significantly, then employing contractors looks less appealing.
