Asda has unveiled plans which will put nearly 300 jobs at risk and leave thousands more at risk of having their pay reduced.
The supermarket chain proposed that some overnight stocking shifts at 184 stores are moved to the day period. This would leave 211 night shift managerial roles at risk.
It noted that the change would also affect 4,137 hourly-paid workers whose roles would be moved to the daytime. This could mean them losing their night-shift pay premium of at least £2.52 an hour. The move will affect workers who currently restock ambient products, such as pasta and tinned goods, and staff restocking frozen food.
