Jobs market slows amid recession fears.
The Recruitment and Employment Confederation said permanent and temporary staff placements increased at their weakest rates for around a year last month.
Pay rates offered to temporary and contract staff fell slightly in September for the first time this year, according to research among 400 recruitment firms.
REC chief executive Kevin Green said: "The jobs market is starting to flatline and may herald a double dip in employment. Whilst there is marginal growth, these figures are the worst we have seen for a year.
"The government must do everything possible to avert the threat of increasing unemployment. This must include avoiding new regulation that could restrict businesses and jobs growth."
A spokesman for the Work and Pensions Department said: "The government is focused on restoring the economy and supporting private sector jobs growth."
