Shropshire Council has announced a second wave of cost-cutting as part of plans to save £60 million by 2013.
The council said a total of 94 senior management positions were under review, with a third earmarked for the axe under plans to achieve savings of £3 million over the next 12 months.
Chief executive Kim Ryley said the changes have been introduced to protect frontline services and provide better value for local people.
"The bulk of current council spending is on staff wages and salaries. Cutting these costs will be essential to meeting the major savings we need to make, and we have set an initial target reduction in management overheads of 20%," he said.
"This is greater than for other staff groups, and will protect resources for our frontline services.
"We are now at the stage where we are working closely with staff and the trade unions to make these changes quickly and effectively.
This will remove uncertainty for our staff and avoid disrupting their work."
Councillor Keith Barrow, leader of Shropshire Council, said the cost-cutting exercise was essential for the future smooth running of the authority.
"People want us to improve efficiency and save money, which is exactly what we are aiming to do," he said.
"When I became leader of the council, I made a promise that we would continue to deliver good quality services for the people of Shropshire, at a cost we can all afford.
"It's precisely for that reason that we have to take prompt, decisive action like this, which will make the council a more efficient and streamlined organisation for the future."
