ROGUE shopkeepers in Scotland could be dialling up trouble if they pay workers less than the national minimum wage.

Union leaders are urging staff to phone a government hotline - 0845 600 0678.

Usdaw is backing a crackdown on employers in the retail sector who are refusing to at least match the minimum wage for adults of £5.35 an hour.

The Government has warned rogue retailers they will be fined £200.
