  ***stress**faced by the operator must be reduced to the minimum possible, taking into account ergonomic*
  *principles such as:*
  
  •*allowing for the variability of the operator’s physical dimensions, strength and stamina,*
  •*providing enough space for movements of the parts of the operator’s body,*
  •*avoiding a machine-determined work rate,*
  •*avoiding monitoring that requires lengthy concentration,*

  **EU directives and regulations in other policy areas influence OSH**or contribute to better OSH, such 
  as the Directive 2003/88/EC concerning certain aspects of the**organisation of working time**, and 
  Directive 2019/1152 on**transparent and predictable working conditions**in the EU, the**Machinery**
  **directive**2006/42/EC with some specific health and safety requirements, and also the**CE marking**of 
  products as conforming with safety, health and environmental standards. 
  
  The quantitative and qualitative**degree of compliance and of implementation of the EU OSH**
  **directives**at workplace level is a constant topic in evaluation studies and expert meetings**.**
  
  A**comprehensive evaluation of all EU OSH directives and their practical implementation**was 
  commissioned by DG EMPL in 2012 and published in 2015, analysing the relevance of the directives, 
  their effectiveness, and the level of the implementation or compliance, based on literature, studies in 
  each Member State, expert interviews and surveys. 350,351
