text: **Figure 2: Risk factors that can adversely affect mental wellbeing – EWCS8 and ESENER9**
  
  A major difference between the ESENER and the EWCS survey is the respondent. In ESENER those 
  persons who are most familiar with OSH or responsible for OSH in an enterprise were asked whether a 
  certain risk factor exists in the enterprise; in the EWCS survey workers themselves were asked whether 
  they are exposed to a risk factor.
