The number of women taking part-time jobs because they cannot find full-time work has increased by 123,000 in recent months, according to the Equality and Human Rights Commission.
There are now 6.6 million people working part-time, the highest number since records began.
The Office for National Statistics found that more than one million people are working part-time because they could not get a full-time job.
In some cases bosses have demanded they give up full-time jobs to reduce wage bills.
Some bosses have claimed that workers must accept fewer hours to save jobs – only to push job cuts soon after.
Job insecurity and part-time working has a dramatic effect on people’s lives.
In the past year, one in five young people aged between 18 and 24 – more than a million people in total – have either moved back to live with their parents or have stalled plans to move out.
