PART-TIME workers in Ellesmere Port and Neston are set to lose £45 a week in working tax credits after changes to qualifying hours.
The number of hours needed to qualify for the payments has increased from 16 to 24, the GMB congress was told.
A total of 20% of GMB members working in retail report they may be better off on the dole after the tax credits changes in the last budget, as two-thirds stand to lose more than a quarter of their weekly income.
In Cheshire West and Chester there were 21,600 in recipient families in work receiving child tax credits and working tax credits as of December 2011.
