People leave work because of “limited recognition and praise” but they stay for “exciting, challenging work.” If the work is interesting but there is no recognition, will people leave? If the work is uninteresting but they are receiving praise, will they stay? I think both answers depend on the money being made, i.e. the relationship between these two responses it money. If your making a considerable amount of money boring work and no praise might seem unimportant. Then challenging work and praise do not matter if you are not seeing much money from them. My experience for the reason why people change jobs is more money or higher, more responsible positions (that, as such, offer more money). In our culture, receiving more money is a sign of praise and more challenging work (doctor, engineer) offers more money. It is said that the importance of an object to a society is measured by how many words we have for it. Well money can be called cash, dough, moola, currency, and many more.
