A widely-publicized trial program evaluating six-hour work days in a Swedish nursing homes may end early next week due to lack of funds.

Early results of the trial, conducted in the Swedish city of Gothenburg, showed positive results. The sick leave for nurses employed at the nursing home dropping to half of the average for the rest of the city’s full-time workers. A consultant working on the trial also noted that nurses seemed happier, and the quality of care had improved, Swedish website The Local reported.

The city’s council was set to meet Thursday to discuss the future of the project, which officials said was “unfair” to continue because it isn’t fiscally sustainable. While the decrease in sick days and absenteeism was promising, shorter days are “not the recipe” for fixing employee burnout, one official said.

The six-hour work day trial, first announced last fall, kicked off in February and was set to run two years.
