Stoke-on-Trent City Council review of agency workers use
The use of agency workers from contractors to consultants, is to be reviewed by a Staffordshire council, as it looks at ways to make savings.
Stoke-on-Trent authority estimates another £100m in savings will have to be made over the next three to four years.
The review, by councillors, is expected to take six to eight weeks.
Council leader Mohammed Pervez said the review would be "comprehensive" and would "examine all council functions".
"It will provide a fuller understanding of where non-council payroll staff are used and will ask challenging questions of whether they are needed, what value they add, and whether savings can be made."
The council said it carried out a similar review in 2009 and "considerable work has been done since then to ensure that the use of non-council payroll staff is minimised as far as possible".
