A further 1,300 jobs are to be axed at Derbyshire County Council bringing the total to more than 3000.
The council previously said 2,000 jobs would have to go by April 2015 in order to save £100 million following government spending cuts.
Today's announcement comes after the authority revealed it needs to continue making massive savings of £164 million through to 2017.
This is because the authority is expected to get less money from the Government than initially hoped, with Whitehall keeping a tight rein on spending as the recession continues.
The councillor in charge of finance John Harrison said job cuts needed to rise to 3,300 and he could not rule out privatising some council services.

"The latest job losses need to be put into perspective. They only account for 4% of the workforce and the number of compulsory redundancies will be very few. But nevertheless we regret having to do that."
Opposition leader Anne Western said services were bound to be affected.
Only two weeks ago, council leader Andrew Lewer said they were on track to make the savings it had planned, possibly even exceed those targets.
But now officials studying budgets over the next five years have warned further cutbacks will be, in some cases, twice as big as previously estimated.
The amount of money the administration says it will have to save in the financial year to April 2014 has more than doubled to just under £25 million.
