Your employer cannot see your answers. Effectory does not disclose personal data under any circumstances.
Please note: the answers to the open questions of the survey, although anonymous, are included verbatim in the report. Your manager has access to the report, so he or she can read exactly what you have written.
Your employer can also see the response rate for the survey group. After the closing date of the survey, a total report is generated on the group level. This result consists of the combined answers of the participants who filled in the questionnaire within one survey group.
