The temporary staff have been told that the rate cut comes into effect on 5 December and that they have until Friday to decline the offer, according to The Register, which has seen the leaked information.

“Should you confirm your non-acceptance by Friday 11 November 2011, then please accept this communication as notice on your current assignment at Barclays Capital to finish on Friday 2 December 2011, or on your current assignment end date if sooner,” the notice said.

In addition, staff have been told that they must take a 10-day holiday – including the bank holidays – before the end of December.
