Essex County Council has announced it is cutting up to 275 managerial posts.
The cuts will be met through retirement, normal staff turn-over, voluntary redundancy and not filling existing vacancies, the council said.
The council said reducing the layers of management would help bring "quicker and sharper decision-making and... lead to enhanced local services".
It said frontline services would not be affected and it was working with public sector unions.
The proposed cuts represent 2.5% of the organisation's core workforce of 10,900 employees or 16.5% of the council's 1,648 line managers.
