Why is someone allowed to continually sub to an umbrella but not a normal company? The actual outcome is no different you're just giving money to parasites.
I am sure they are not subbing to an umbrella, they still sub to who ever the employer is, employer deals with all hiring and firing they just do the admin
They manage payroll and do right to work checks and other admin sort of stuff, so contractor pays them and they then pay the subby, just means the liability of deducting cis is on them. I would imagine there are fees both ends for what they do for the main contractor and the subby so they effectively get paid twice to run payroll.
Suppose if you have a lot of people working for you it's easier to just pay Hudson one payment rather than how ever many people you have and all the deductions and then paying that bill when it's due.
Reality is majority of people who are being paid by them aren't self employed, and are just disguised employees and should all be on PAYE. Llunless it's changed look at all the lads who work for mv Kelly they are not self employed in any way, given vans told where to work, when and how to do it, the same goes for a lot of the construction trades
