New figures suggest that dodgy umbrella companies could be costing thousands of temporary workers through lost holiday pay.
Freelance support group IWORK calculated that at an average salary of £26,000 per year, umbrella workers would be missing out on more than £3,000 of holiday pay.
They estimate that if just 2% of the UK’s 1.6 million temps are affected, they would be shortchanged by a collective £97 million per year.
