Some companies have tested a four-day working week with no loss of pay. In one trial, employees reported lower stress and better work-life balance, while managers noted that productivity remained stable. However, the trial lasted only six months and involved mainly office jobs. Researchers warn that results may differ in sectors such as health care or retail, where continuous presence is necessary. They recommend longer studies across more industries before drawing general conclusions.
