The TUC says families in Wales are experiencing "a huge squeeze" on their incomes.
Its research, published today, shows wages here have fallen by 7.3 per cent since 2007.
Families are still really struggling to make their money go far enough - and are often having to go into debt - as they experience a huge squeeze on their household incomes.
With real wages still falling, most people are being forced to use their credit cards or their dwindling savings if they need to purchase anything beyond the most everyday of items.
Workers' real hourly pay rates have taken a hit over the past five years because wages have failed to keep up with inflation. But this fall is also a result of the worrying increase in insecure and short-hours employment.
And in many cases when people have lost their jobs, and are fortunate enough to find work, they are forced to take jobs with fewer hours and on lower rates of pay. This is not the way to build a strong economy - the UK needs far more better jobs on much better rates of pay.
Wages in Wales have fallen by 7.3 per cent since 2007, according to research published today by the TUC. That's worse than the UK-wide average drop of 6.3 per cent. Across Wales and the UK as a whole, men have seen their pay squeezed harder than women.
The figures compiled by the TUC show that - after taking inflation into account - weekly pay packets in Wales have fallen by an average of £32.36 since 2007.
Flintshire is the hardest hit county in Wales, where average hourly pay has fallen from £11.75 in 2007 to £10.31 last year - a 12.2 per cent real terms drop.
