We highly advise you to share the well-being driver scores for the company each measurement.
Why?
There are several benefits:
Response rate: Showing that you use it and that you care as a company will tell the employees that they are heard and emphasize why participation is important.
Trust: Being transparent encourages trust in your management of the company. Even when numbers are not as you would like - this vulnerability will make the employees respect you even more.
Interpretation and action: Telling them what you understand from the numbers; what you have reflected upon; what surprised you; what makes you curious, as well as letting them know what you (in the management) will do about it, will let them know that you take it seriously and want to actually act on it.
