The contract offered is on a self employed basis.
They've offered £150 as a day rate. My previous employed position was about double that (including pension & benefits)
The advertised job that I went for was about £250 if you work out the package on a daily rate.
I have a feeling they're taking the piss!
The initial reason for applying for the job, except that I'm unemployed was that it was based in my home town where previously I was away a couple of days a week.
