Financial guru Martin Lewis has said that around 500,000 UK employees who are earning a minimum wage may be being underpaid, and has revealed how those who are due extra money can claim it.
The MoneySavingExpert creator explained that this applies to those who need to buy work supplies such as tools or clothing.
Others may be underpaid as a result of unpaid working time — for example journeying to work early in order to open up the business for the day.
