The government has named businesses that failed to pay some staff the minimum wage.
The official list includes Northern Ireland businesses, horse racing trainers Alan King and Lucinda Russell, and retailer B&Q.
Those named are expected to repay the money owed to staff.
Separately, official figures suggest that wages are falling behind in real terms.
That is an economic warning sign.
Prices are climbing more quickly than wages, leaving workers feeling the squeeze.
The government list and the pay data demonstrate financial strain for workers.
Officials said enforcement action would follow for employers who broke minimum wage rules.
