P&O Ferries will be forced to “fundamentally rethink their decision” to sack nearly 800 workers, according to Transport Secretary Grant Shapps.
The Cabinet minister made the claim as he set out a series of measures in response to the redundancies.
These include plans to create “minimum wage corridors” on ferry routes between the UK and other countries.
He will also urge ports to refuse access to boats carrying seafarers paid below the minimum wage, and ask the Insolvency Service to consider disqualifying P&O Ferries chief executive Peter Hebblethwaite from acting as a company director.
Speaking in the House of Commons, Mr Shapps said: “P&O Ferries’ failure to see reason, to recognise the public anger, and to do the right thing by their staff has left the Government with no choice.
“I am today announcing a package of nine measures that will force them to fundamentally rethink their decision.
“This will send a clear message to the maritime industry: we will not allow this to happen again.
“Where new laws are needed, we will create them. Where legal loopholes are cynically exploited, we will close them. And where employment rights are too weak, we will strengthen them.”
P&O Ferries sacked its crews and replaced them with agency workers on March 17.
The minimum wage in the UK for people aged 23 and over is £8.91 per hour.
Mr Hebblethwaite, whose basic annual salary is £325,000, told MPs on March 24 that the average pay of the agency crew is £5.50 per hour.
