How do I access the comments from the latest employee survey?

To access the comments, you need to have authorisation to do so. The authorisation is granted by the company's superuser (under Advanced settings on the user card).

To export all comments to an Excel file, you first select survey and then click on the Comments button. You obtain comments for the survey and level of detail you have selected.  

To obtain an in-depth analysis of the figures, it is important to read all comments. The optimum effect is achieved by also displaying the comments when you review the results, and asking the team to develop them in order to obtain as fair a picture of the outcome as possible.
