From an article posted on Linkedin by Oleg Vishnepolsky regarding why good employees leave:
Three workers are working by the side of a road, breaking stones. A passerby notes that one of them is very unhappy, another is ok and the 3rd one is very happy. Curious as to what is going on, the passerby asks each one.
The first one, the unhappy one, says I am breaking stones. Hard work, hot.
The second one, contented one, says I am making a good living. I have a family to feed.
The third one, the happy one, says I am ....... building a temple.
Make sure you can tell your team what temple they are building.
If you can not answer the question, they will answer the call of a friendly recruiter.
