Yes the gender pay gap is real and it's unfair. Traditionally, senior roles are dominated by white upper middle class men which skews the figures in favour of the male half of the workforce. Unfortunately not all male workers are executives, both men and women have suffered poor wages and working conditions at the hands of the 'men in grey suits'. Doesn't matter how many women they appoint at the top or push into middle management, the ordinary worker male & female still gets sh*t on.
Treat everything in life the way a dog would- if you can't eat it or foc it, forget it.
