Sussex Police announced that more than 300 employees would leave the force in the coming three months.
It said that the main consideration when deciding whether to accept the 307 volunteers for redundancy was the impact of the loss of each job on the service provided to the public.
The voluntary redundancies are being made as the force tries to save £52 million by 2015.
It said last September that it would have to cut 500 officers and 550 other staff from its headcount.
The 307 volunteers for redundancy would reduce the need for compulsory job losses, the force said.
No more police community support officers (PCSOs) are being taken on and the force may shut Hove Police Station and open other police stations for fewer hours to save money.
Chief Constable Martin Richards said: “We have to make significant savings and we have been open about having to lose posts.
“This scheme, suggested by Unison, provides an opportunity for individuals to leave the organisation voluntarily with an enhanced payment, and, at the same time, helps the force save money and reduces the need for compulsory redundancies.
“There has been a lot of interest in the scheme and around 70 per cent of the applicants were accepted.
“They will be leaving the organisation in the next three months.
“The panel looked at a number of factors when making their decisions but their primary consideration was the impact that decisions would have on our service to the public.
“For many it would have been a difficult decision to apply for the scheme, one which in normal circumstances they would not necessarily have made.
“We are supporting staff as they leave the organisation and thank them for their service and wish them well for the future.”
