Last time I was on holiday to the extent that I could unwind, de-stress, hear myself think I concluded that I did not want to go back. I contacted a former coworker just to get some feelers out there about how the industry was doing. Before my holiday was over I had a signed job offer, and I resigned as soon as I got back to the stressful job.

Lesson learned: Give your employees perpetual emergency brain with no time to step back and reflect. Otherwise they could start to evaluate their situation and whether they really need to stay.
