Calls for zero-hours contracts to be scrapped in Staffordshire and Cheshire
The Trades Union Congress are calling for them to be banned altogether
Most zero hours workers are "stuck" on their contracts, highlighting the need to ban them, according to a new report.
The TUC said hundreds of thousands of workers are being trapped in low-pay and insecurity, with bad employers "parking workers on zero hours contracts for years on end".
Its study of official data found that two in three zero hours contract workers have been with their current employer for over a year, while one in eight have been with their employer for over 10 years.
Only 7% of zero hours workers have been with their current employer less than three months, said the TUC.
The latest data showed there are 1.15 million people on these contracts.
Black and minority ethnic women are nearly three times as likely to be on zero hours contracts as white men, said the report.
TUC general secretary Paul Nowak said: "Everyone should be treated fairly at work, but too many workers - especially black and ethnic minority women - are trapped in low-paid jobs on zero hours contracts.
Few rights and no guarantee of shifts
"Bad employers are parking workers on zero hours contracts for years on end." added Paul.
"These precarious contracts hand almost total control over workers' hours and earning power to managers, making it nigh on impossible to plan budgets and childcare.
"Insecure work has boomed on the Conservatives' watch over the past 14 years, with the number of workers on zero hours contracts hitting the one million mark.
"That's why a ban on zero hours contracts is long overdue. Working people should have a right to a contract that reflects their regular hours of work.
A Department for Business and Trade spokesperson said:
“Zero-hour contracts offer flexibility for people who may need to balance work around personal commitments whilst helping employers with less demand for permanent staff.
“We continue to tackle unfair working practices through the Workers Act, giving workers the right to make a request to their employer for a more predictable working pattern, and boosting the National Living Wage for millions of workers to £11.44 an hour.”
