Full-time workers could be given the right to ask their employers to work a four-day week under government plans to increase flexible working.
Employees would still have to work their full hours to receive their full pay but could request to compress their contracted hours into a shorter working week, according to plans first reported by the Daily Telegraph.
Conservative shadow business secretary Kevin Hollinrake claimed businesses were “petrified” about the plans.
However, ministers insist they will not impose the change on staff or businesses.
“Any changes to employment legislation will be consulted on, working in partnership with business,” said a spokesperson at the Department for Business and Trade.
They added that the plan for more flexible working was instead designed to increase productivity and help get more people back into work.
Currently, employees have the right to request flexible working but employers are only required to deal with requests in a “reasonable manner”.
Earlier this year, Morrisons scrapped four-day working weeks for its head office staff following feedback.
In order to make the four-day week work, staff had to work some Saturdays, which resulted in complaints and dissatisfaction.
In July, Asda shelved a four-day week trial after staff complained that their longer shifts were too demanding.
Labour came to power earlier this year promising to make flexible working the default from day one for all workers, except where it was not feasible.
Details are expected in the autumn when a law to create a new package of workers’ rights is expected to begin its journey through Parliament.
Labour has pledged to repeal some anti-trade union laws, restrict the use of zero-hours contracts and expand flexible working arrangements.
Prime Minister Sir Keir Starmer calls the proposals “the biggest upgrade to workers’ rights in a generation” and Deputy Prime Minister Angela Rayner argues they will be “good for the economy”.
But the Conservative opposition claims the approach would damage business and lead to reduced productivity.
“Despite warning after warning from industry, Angela Rayner is pressing ahead with her French-style union laws that will make doing business more expensive in the UK,” Mr Hollinrake said.
In 2022, several UK companies took place in a six-month trial to test a four-day working week, which saw workers receive full pay for working fewer hours.
Tyler Grange, an environmental consultancy, took part in the trial and in 2023 told the BBC it was sticking with the working pattern.
Simon Ursell, its managing director, said the first month of the trial had been “a bit white knuckle”.
But the firm said it found the extra day off boosted staff happiness and even resulted in more people applying to work there.
However, the experiment did not work for Mark Roderick’s engineering and industrial supplies company Allcap.
“As opposed to 10 normal workdays, we found that employees would have nine extreme ones – once they got to their scheduled day off they were exhausted,” he said last year.
“Once we factored in holidays, sickness and caring responsibilities, we also struggled to find cover for an employee on their rest day,” he said.
