Explain the why and the privacy.
Tell people what the survey is for, who sees results and how answers stay anonymous. A short message from a leader raises trust.
Make taking part easy.
Give clear dates, a link that works on phones and time at work to answer. Send one reminder, not many.
Share results and act.
Share headline results honestly, including hard ones. Choose two or three actions and say when you will report back.
Silence after a survey harms the next one.
