Late in December 2015 Sports Direct announced a 15 pence per hour increase for staff currently receiving less than minimum wage, taking them above minimum wage, the annual cost of this was said in the announcement to be ~£10 Million (GBP); however it was immediately noted that £0.15p × 37.5 hours × 19,000 staff × 52 weeks = 5,557,500 (~£5.5 million), this and other factors resulted in many (including Unite) calling it a "PR Stunt". Workers on zero-hours contracts are not included in the rise and neither are those already paid more than minimum wage (management/supervisors etc.) therefore the 19,000 staff above is actually substantially fewer.
