DefinitionRetention (リテンション) is the general term for measures that encourage needed staff to stay with the organization instead of leaving.
ExplanationExamples include revising evaluation and pay, offering flexible work arrangements, and providing chances to grow and places to talk about concerns. When experienced people leave, the money and time spent hiring and training them are lost, so companies put as much effort into keeping people as into hiring new ones.
AnalogyLike plugging the hole in a leaky bucket before you keep pouring water in.
Memory hookRetain means to keep or hold on to. It is the same word as in retention period, the length of time data is kept.
