North Lincolnshire Council has announced it is shedding five senior managerial jobs in an effort to save £400,000 a year.
The council said the changes had been agreed through early retirements and people leaving their jobs.
The most senior post to go is the deputy chief executive.
Council leader Mark Kirk said the changes would protect frontline services in the wake of a 12% cut in the amount of government funding.
Mr Kirk said: "It has always been our intention to cut from the top down in our reshaping as the details are worked out.
"Streamlining the top tier of council management is the best way for us to make significant savings without compromising our service to the public."
