But as anyone in the age group knows, most of us bust our arses at work - and now, a study can back this claim up too.
A study conducted by blow LTD has found that amongst the UK's female workforce, millennial women (aged between 22 and 29) work the hardest.
This age group works 1,692 hours a year on average - 136 hours more, or roughly 18 typical working days, than most UK working women.
Women based in London also work a greater number of hours on average. These women complete 1,631 hours a year, which is 75 hours or ten typical working days more than most of the UK's female workforce.
This is closely followed by women in Scotland (1,626 hours a year) and the North West (1,570 hours).
The number of hours worked appears to go down in age, with women aged 30 – 39 working 1,631 hours a year, and women aged between 40 and 49 1,515 hours.
Overall, the number of women in employment hit a record 14.6 million at the end of 2015, with nearly 1 million (975,000) more women in work than five years ago.
So next time an older person tells you you have it easy at work, tell 'em to do one.
