The Pay & Work Rights helpline (0800 917 2368) will enable them to get advice over the phone about their workplace rights, including:
- agricultural minimum wage
- working time (48-hour average working week)
- employment agency standards
- gangmaster licensing.
Previously, calls on each of these rights were taken by separate government bodies.
The launch of the single helpline comes as a poll showed that nearly half of people (48 per cent) wrongly thought employment agencies can charge workers a fee for finding them a job.
McFadden said: "This Government has done a lot to improve rights at work but it's also essential to make sure these rights are properly enforced. A simple system for reporting abuses and giving advice and information to employers and workers is a critical part of that.
"By consolidating the current complex system of different helplines for different issues into one single number we are making it easier for workers to report abuses and for Government to respond."
