Scottish contractor Edward Mackay has been fined an undisclosed sum for failing to pay four workers the minimum wage, totalling more than £50,000.
The Highlands-based firm is among 260 companies to have been named and shamed by the Department for Business, Energy and Industrial Strategy (BEIS) for breaches relating to the minimum wage.
Edward Mackay, which provides construction and civil engineering services, failed to pay four workers £51,403.65, BEIS said.
The 59-year-old company, which was first established as a road haulage firm, was fifth on the list of companies ranked by how much they underpaid, just below retailers Primark and Sports Direct.
In total, government investigators identified £1.7m in back pay for workers and fined employers £1.3m for underpayment.
The government said it will spend a “record” £25.3m on minimum wage enforcement this year.
Since the naming and shaming scheme started in 2013, it has identified £8m in back pay for 58,000 workers, with 1,500 employers fined a total of £5m.
Business minister Margot James said: “There is no excuse for not paying staff the wages they’re entitled to and the government will come down hard on businesses that break the rules.”
Edward Mackay has been contacted for comment.
