Employers who are repeatedly found to not be paying staff the national minimum wage will be heavily penalised from the beginning of next year. Gordon Brown has announced a 50% increase in the budget to £9m from April to police businesses that fail to pay workers £5.35 an hour. Measures will include tracking down, fining and prosecuting minimum wage offenders. The government is concerned that enforcement procedures adjust to the changing UK labour market, which has seen an increase in the use of migrant workers.
