It’s important to remember that employee engagement is more than employees feeling good about the work they do or liking the people with whom they work. It’s about an employee feeling that they have a role in the company or on the team, that they make a difference, and that they aren’t just a cog in the corporate wheel.
Imagine you were working as a clerk in a grocery store, and your manager suspected you of stealing some product off the shelf. She has no concrete evidence, only hearsay from a co-worker. An investigation turns up nothing, and you continue working as though nothing had happened. But the manager notified your employer, and your employer added your name to a database of suspected employee thieves, which all sorts of retailers of all sizes subscribe to in order to avoid hiring persons of questionable character.
