Shropshire Council could cut 540 full-time equivalent (FTE) posts in a bid to cut costs by becoming a smaller organisation.
The unitary authority, which employs around 3,500 staff, is facing a budget gap of £62.5m this year and estimates it could save £27m by resizing.
Earlier this year it launched a voluntary redundancy programme – and said at the time it aimed to lose 300 FTE posts.
The council has also begun reviewing all posts to consider whether any vacancies could be removed.
It is paying external consultants to identify further savings.
Council leader Lezley Picton said: ‘Our legal duty to set and maintain a balanced budget means we must leave no stone unturned and that means making decisions we have never wanted to make.
‘We are working through the resizing steps carefully to limit any adverse impact to our statutory duties and focusing our resources on those services that support our most vulnerable residents.
‘We will change the way we work to deliver these as efficiently as possible, doing the right jobs in the right way, as the council we need to be.
‘Our financial position is still exceptionally challenging, and our financial survival is key.’
