Office for National Statistics (ONS) figures show the typical full-timer worked 37.4 hours in autumn 2015, compared with 38.5 two decades ago.
Recently working hours have resumed the downward trend disrupted by the crisis and recovery.
We’ve also been facing fewer crazy weeks.
The proportion of full-time staff working more than 50 hours a week fell from 16 per cent in 1995 to 11 per cent in 2015.
Those working a more normal week, between 36 and 40 hours, rose from 30 per cent to 36 per cent between 1995 and 2015.
The ONS said the fall in working hours could either be a deliberate choice by workers to give less time to their jobs as they feel more comfortable as the economy picks up.
Or it could be a temporary change: hours could still rise, but wages might not follow.
The statistics body added that the decline of extra-long work weeks could be linked to the growth of service industries and laws like the Working Time Directive.
The ONS also said workers could be more confident in taking time off work.
The ratio of actual and usual work hours, which captures illness and holiday, rose strongly between 2010 and 2014. This mean fewer people were taking time off.
The measure has moved back towards its pre-downturn level in the last 18 months.
This could mean we’re making the most of strong real earnings, having the confidence to take more holidays compared with recent few years.
More depressingly, it could mean companies have temporarily cut workers’ hours due to the recent slowdown in the UK’s growth.
