When I see leaders dealing with the choice to let their workforce work onsite or remotely, I often hear discussions about past practices and the need to have close contact.
Those are important considerations, but the more important conversation is what employees want from their position and work life. The world has shown everyone remote ways to do the job, and the discussion should be about how to take advantage of the knowledge. The key is that people are finding they have a choice, and the decision to leave may be easier than ever. All most people want is a say in where they work so that they can adjust their work to their life instead of the other way around.
If leaders cannot find a way to accommodate them, they may continue to see people leave.
