Hull, Bradford and Rotherham have missed out on the recovery seen in some cities through recent unemployment figures, according to the GMB union.
They claim that gross domestic product (GDP) levels are 5.7 percent below those of 2007 and that average earnings are down 13.8 percent in the same period.
The GMB says Hull's employment rate is 11.6 per cent below the national average, while Bradford's is 7.4 per cent lower and Rotherham's is 6.6 per cent lower.
Fears of a "cost of living crisis" have been reignited after regular wages growth fell to a record low of 0.7%.
Overall pay - including bonuses - climbed by just 0.3% compared with the three months to May in 2013, which is the lowest increase since the financial crisis in 2009. The figure is skewed by higher bonus payments in April 2013 that took advantage of tax rate changes.
However, the increase of regular pay - excluding bonuses - was at 0.9% in the three months to April before sinking to an all-time low of 0.7% growth since records began in 2001.
Len McCluskey, general secretary of the Unite union, said: "With wage growth at its lowest rate since 2001, while inflation continues to vastly outstrip wage rates, ordinary people are working harder and getting poorer."
