As a participant in a survey, your answers will be completely anonymous. Lattice will remind each participant of this at the start of the survey and at the bottom of the survey:
How do I know my responses are anonymous?
Survey responses will never be tied to employee names. Additionally, to ensure anonymity for participants, a minimum of three employees must answer a question for results to be revealed to the admin. Admins will have the option to raise the anonymity threshold for your organization, however it can never be lower than three.
