My ordered list, having seen a lot of departures lately, would be: 1. Fair compensation, meaning don’t make people feel like they’re suckers for sticking around. 2. Team quality, since any move to a new job means you might have to work with bad people, so if you currently work with good people that’s a huge hurdle, especially for engineers. 3. Useful work, i.e. useful for keeping interested, useful for advancing careers, useful for making the company successful (in that order). 4. Work environment, so your valued Employees don’t think they’re just expensive meat on a stick. That probably means less open plan, not more free food. 5. Flexibility, because not everyone wants or needs the same thing.
