Re: IR35 idiocy
Given the number of number of IT contractors in the country, it's highly unlikely that all of them can quit and look for other jobs either in this country or abroad. There simply aren't enough jobs available. It's the same for demanding higher rates. Some people will be successful and others will just have to accept what they are being offered.
Only the best contractors will be able to pick and choose their jobs and rates. It may come as a surprise to some people, but not all contractors are high performing experts that we expect. There is a mix of good and bad, just as in any industry. I have worked with some truly amazing contractors, but also contractors that I am amazed managed to get past the interview.
