This can have 2 reasons:
1. You recently worked for your old employer and the invitation was sent at their request. This means that this employer appreciates your opinion about the organization and would like it to be included in the survey. It may be that your former employer would like to ask you some questions about your departure and what the organization could have done better.
Would you rather not complete the questionnaire?
No problem. You can of course choose not to complete the questionnaire.
2. Your e-mail address is still in the HR file of your old employer. In this case, you can contact the Effectory Helpdesk via this page to indicate that you are out of service. They will delete your data. You will then no longer receive any messages about the survey.
