The government has named businesses that failed to pay some staff the minimum wage.
The government list includes Northern Ireland businesses, racing trainers Alan King and Lucinda Russell, and retailer B&Q.
Those named will have to repay the money owed to staff.
Separately, recent reports suggest that wages are trailing inflation.
That is a worrying economic indicator.
Prices are increasing at a faster rate than earnings, leaving workers with less spending power.
The government list and the pay data demonstrate financial strain for workers.
Officials said further steps would follow for employers who broke minimum wage rules.
