Full-time working fathers out-earn their childless counterparts by more than a fifth, research suggests.
On average, fathers working full time get a 21% "wage bonus", the study based on 17,000 workers aged 42, concluded.
Fathers living in Britain with two children earned 9% more than those with just one, says the research by centre-left think tank IPPR for the TUC.
Full-time working mothers of the same age saw a "wage penalty", earning 11% less than their childless colleagues.
The report said the reasons for the "fatherhood bonus" were not clear, though they were likely to relate to hours worked, increased effort and positive discrimination.
It cited official labour market statistics showing full-time working men with dependent children worked on average half an hour longer each week than men without children.
It noted the same statistics showed that full-time working women with children worked about an hour less a week than those without children.
It also referred to a study which suggested there was a "long-term scarring effect" on the future earnings of women who initially take on part-time responsibilities when they return to work after maternity leave.
t said analysis based on fathers in the US found that increased work effort accounted for 16% of the fatherhood bonus.
The TUC said international studies cited in the report found that CVs from fathers were scored higher than identical ones from non-fathers.
So this pretty much explains the mythical "wage gap" between men and women. However I'm sure there will be some idiot feminazi, who will try to spin it around.
