Roadshows are being held in Liverpool on Wednesday 14th and Thursday 15th January; Blackburn on Friday 16th January; and Manchester on Saturday 17th and Sunday 18th January.
The "It's Your Call" campaign was launched in Downing Street by Business Secretary Lord Mandelson in November and is touring the UK over a three-month period, stopping off at 28 towns and cities, giving workers advice on their entitlements and how to make a complaint if they have been underpaid.
North West Minister Beverley Hughes said:
"The national minimum wage has benefited millions of working people in the UK since it was introduced a decade ago. About 132,000 employees in the North West have been helped by the latest increase in October last year.
"The government's 'It's Your Call' campaign is helping make sure that workers across the country are getting the wages they are entitled to, and that they know how to get them if they are not. It is also crucial that employers know and respect their responsibilities. Anyone who thinks they may not be getting the minimum wage should call the helpline on 0845 6000 678."
Lord Mandelson said:
"The minimum wage was introduced when I was Secretary of State for Trade and Industry 10 years ago and I am so proud to see the difference it has made to the lives of millions of hard working people across the UK.
"More than one million workers benefited from its increase last month and it's important that we make sure everyone knows what they're entitled to, that's what this campaign is all about.
"Of course, most businesses treat staff fairly, but the small number who cheat their workers are flouting the law and undercutting honest competitors.
"Our changes will make sure everyone caught not paying their workers properly faces a stiff penalty - we are determined to ensure workers are paid fairly."
Royal Assent for the Employment Act has paved the way for new penalties to come into force in April, as part of government's crackdown on those who try to exploit workers.
The changes introduce unlimited fines for non-compliance for the most serious cases, removing the maximum limit of £5,000.
The roadshows will have facilities to report cases of abuse, while fully trained staff will be on the spot to give expert face-to-face advice.
Visitors to the events will also hear local people tell their stories of underpayment and the help they received tackling wage abuse.
More than one million people across the UK benefit from annual rises in the National Minimum Wage. On October 1st, rates rose to £5.73 for workers aged 22 and over; £4.77 for 18-21 year olds and £3.53 for those aged 16 and 17.
Anyone worried they may not be getting the National Minimum Wage can call the NMW helpline on 0845 6000 678. Support is offered in more than 100 languages and callers can remain anonymous if they wish.
