IT contractors protest outside Parliament
Then they aren't doing it right - when we did it back in 1999 we were inside, nice and warm in the lobby, green carding our MP's (and going for a pint afterwards, on expenses, of course).
Must admit thinking the writing was on the wall though as Andrew Lansley didn't really give me many assurances.
And so 20 years later we see the death of computer contracting (taking with it similar professions, I imagine).
As for the comments above - I still paid NI. A few pounds a year over the threshold, enough to guarantee my state pension, the wife's maternity pay etc etc.
