Advertised Hourly Rate (net of umbrella)

[Kanye]

This doesn't make sense.

If they've advertised a rate of £100/week and the umbrella take fees + national insurance + tax and give you say £60 then thats normal.

If they've advertised a net rate of £60 as the day rate that is not standard, but shouldn't come as a surprise.

Just seen my first weeks [sic] payslip, and the money is lower than I expected, gone back and found that the rate I have been quoted is an "umbrella rate", so therefore the additional money I was expecting will not be forthcoming.
I have never been for job [sic] where I have been offered a rate in this manner, and its [sic] obviously to inflate what is a very low rate. Is this common place?

What "additional money" did you expect, and whence?
