Tesco is to cut pay on Sundays and overtime rates for workers in an effort to cut costs.
Employees receiving double time for Sundays and Bank Holidays will reportedly get time and a half from July, a 25% drop.
Higher pay rates for overtime and working from 10pm until midnight will also be revoked, with extra hours paid at the standard rate.
Staff are expected to be informed of the changes this week.
A Tesco spokesman told Drapers: ”Tesco continues to be an industry leader in total pay and benefits. All hourly-paid store colleagues will receive an increase in base rate of pay, and over 85% of all our store colleagues will see an improved total package. Where there are changes to premium rates, colleagues will be compensated with earnings protection over a considerable period.”
