The agency now states it must use an intermediary tax management company, presumably to 'insulate' itself from unforeseen liabilities.
However the cost of this (~2 eur/hr) is now being deducted from the net rate paid.
I thought I was negotiating an hourly rate for my contracting company, not for the intermediary's benefit !
Shouldn't the agency be taking the hit since it's really an insurance for them ? Also it's not the rate I specified during negotiations - if I'd known I would have upped by the required 2 eur.
I did state that the required rate to be the minimum economic amount for me to consider the work, given the overheads and expenses.
