Monsoon was lucky. Had the failure to pay the NMW been after May 2015, the fine would have been £20k per worker rather than 20k maximum.

The government’s preferred method of enforcement, however, is “naming and shaming” and this applies in other areas too. If the company is a well known brand, it seems to work.

It was forced to repay the money owed to 1,438 workers, as well as a fine of up to £20,000 reduced to just £10,000 if paid within 14 days.

The sister brands claimed the pay gap was an ‘unintentional breach’ of regulations which affected staff working between 2011 and 2013. It did not reveal last night how much fine it had paid.
