Abraham Maslow argued that human needs stack: until the basic ones are satisfied, the higher ones do not motivate you.
The five levels, bottom up: physiological (pay enough to eat and keep warm), safety (job security, safe conditions, a contract), social (belonging, being part of a team), esteem (recognition, status, responsibility) and self-actualisation (doing work that fulfils you).
The claim is that a level only motivates once the ones beneath it are largely met. Offering someone a fascinating project matters little if they are worried about making rent or losing the job.
It explains why pay rises stop motivating. Once pay comfortably covers the lower levels, more of it does relatively little, and the levers that still work are recognition, responsibility and interesting work — which happen to be free.
It also explains the reverse. A business that has just made redundancies has knocked everyone down to the safety level, and no amount of team-building will land until people feel secure again.
Name the level, say what the business could do at that level, and say why it fits this workforce. Listing five levels with no application is a low-mark answer.
