With job vacancies outstripping the number of unemployed people, new data from CV-Library highlighted recruiters’ initiatives to attract top talent.
The research found that job postings for positions offering a four-day week have risen by 89.6% year-on-year.
The positions offer 100% pay for 80% of the hours, as long as productivity remains at the same level.
Whilst there is an increase in all locations in the UK, there is a clear divide in the north and south of the UK as to which employers are embracing the idea.
The locations with the highest year-on-year increase for four-day week vacancies are the south west (191.4%), Wales (148%), the south east excluding the capital (108%) and London (104%).
Those with the lowest are the east midlands (55%), north east (53.8%), East Anglia (70.1%) and the north west (79.6%).
In terms of sectors, all except agriculture and personnel have seen annual increases to four-day a week job postings. The top sectors are charities (492%), distribution (373%), catering (286%), sales (247%) and administration (214%).
Lee Biggins, founder and chief executive of CV-Library, said: “We are seeing a huge increase in the number of four-day week jobs being posted.
“A year ago, these types of jobs were negligible. A lot has changed in both the economy and the job market over the last 12 months and employers are having to seek new ways of attracting new staff, over and above competitive pay and a pension.
"Time will tell if this draws in job seekers, and we’ll be keeping a close eye on application numbers.
“It’s also crucial to see the results of the trials in place and if a four-day working week is viable and sustainable for businesses and not just a short-term solution to attract and retain top talent."
