About 450 jobs are to go as part of £98m budget savings approved by Essex County Council.
The full meeting of the Conservative-controlled authority, which backed a £2.1bn budget, also agreed to freeze its part of the council tax.
It follows a £40m reduction in the government's grant to the council.
The home to school transport budget is being cut by £4.7m, the recycling waste budget by £1.3m and the libraries budget by £1.9m.
No library closures
Changes to library opening times and the mobile library service will be made to make savings, but the council has pledged not to close any libraries.
The local authority said it had limited this year's cuts to £14m, by saving £50m from back office and procurement processes and taking £34m from council reserves.
It has also said it will promote sustainable economic growth by spending at least £1m to help Essex firms create jobs and take advantage of new market opportunities.
The authority at present employs more than 9,000 people excluding teachers and education workers which would take the total to about 38,000.
