text: ***3.1.1 Working time in hours and at atypical times***
  
  **Too many hours of working time and/or working hours at atypical or unsocial times**can put**the**
  **mental**and**the physical health**of humans at risk. It is also regarded as a major**contributing factor**
  **to work accidents**, due to fatigue or exhaustion.16 
  
  The main indicator to describe working time is the**number of the weekly average working hours**of 
  full-time employees. However, regarding its impact on health and safety,**other aspects of working**
  **time are of the same relevance**: 
  
  • How long is the average working day? 
  • At which times and days is this work done (typical, atypical times)? 
  • How often do long working hours take place? 
  • 
  • How flexible are start and end? 
  • How intense is the work during this time (breaks, deadlines)? 
  • Which groups of workers have standard working times and which do not (e.g. depending on the 
  
  Is the work split between two jobs? 
  
  sector or the type of contract, e.g. sub-contracted workers or self-employed)? 
  
  There is a**slight trend towards fewer working hours**for full-time**employees**(not ‘Employed persons’) 
  in the EU27; between 2006 and 2019 the average weekly working time dropped from 40.2 to 39.9 hours, 
  a decrease of approximately 15 minutes.17
