A Berkshire council is to axe 150 jobs under plans to save £9.5m over the next three years.
But Wokingham Borough Council said social services for vulnerable adults and children would not be affected.
Weekly bin collections will continue and a new library would open as planned, council leader David Lee said.
Mr Lee said he hoped the job losses would be met through natural wastage. The Unison union said it was looking to protect as many jobs as possible.
Council tax rise
Paul Bee, from Unison, said: "At the moment what we know is that there is in the sense nothing left off the table.
"What we are looking for is to keep as many services and services in house as we can.
"There is so much expertise and knowledge already in place."
Councillors will vote on the proposals, which also include a 1.9% council tax rise, next week.
Mr Lee said: "We are aiming to achieve [job losses] over a three year period.
"Within that period we will have a natural turnover of staff of 300 and 75 retirements.
"So we are hoping that it will not be compulsory but we cannot rule that out."
