Edinburgh Council is considering proposals to reduce management costs in preparation for government funding cuts.
If approved, about £16m would be saved over the next three years towards the budget savings target of £90m.
It is expected that, in the first instance, about 300 jobs could be affected across all departments.
The proposals, which have come from council officers, cover management posts and "backroom" functions.
A consultation process has begun with unions, and staff are currently being briefed on the proposals.
Any reductions in staff would be handled through a combination of options, including reducing temporary staff, leaving vacancies unfilled, early retirement, voluntary redundancy, and redeployment to vacant posts that need to be filled.
However compulsory redundancies cannot be ruled out.
Council Leader Cllr Jenny Dawe said: "The harsh reality of the UK budget deficit requires us to confront some very difficult decisions.
"We recognise just how concerning this is for staff and we will critically examine the proposals received from directors.
"We will do all we can to support staff and to protect the valued and vital services they deliver for the people of Edinburgh."
The council has taken the exceptional step of presenting these options to the meeting of the full council on 16 September, rather than waiting for the normal budget-setting process in February, to allow more time to manage any changes.
Further savings proposals are being developed which will be the subject of full public engagement over September and October before they are considered by councillors.
