"Results from the group, whose profits rose by 25%, came amid mounting criticism after an investigation by the Guardian revealed that temporary workers at Sports Direct are receiving effective hourly rates of pay below the minimum wage.

Warehouse staff at the company, which is controlled by Britain’s 22nd richest man, are required to go through searches at the end of each shift, for which their time is unpaid, while they also suffer harsh deductions from their wage packets for clocking in for a shift just one minute late.

The rigorous searches of warehouse staff – who are asked to roll up trouser legs and show the top of underwear – typically take 15 minutes and illustrate how concerned management is about potential theft. This typically adds another hour and 15 minutes to the working week and is unpaid."
