If this job is also meaningful (and it would be if we are imagining the ‘perfect’ job for you) one can appreciate what trouble the business would be in if you were to be run over by a bus. The job was so perfectly tailored to your unique self that nobody could replace you in the event of your demise.

In this part of world and perhaps generally, barely 2 out of every 10persons would drive in this mannerism, they remain exceptionally unique in terms of the services they rendered, thus they are hardly replaceable.
The CEO of a supermarket would lay off/sack his shop floor attendants at anytime for simply any reasons because he is well aware that he can always get a new set of attendants so easily.
Workers are treated according to the quality of the services they render, time spent, and the level of their education, especially in this part of the world, additionally, the whole thing can be exhausting at the end of it all, when the pay is discouraging, a pay not fitting the effort and time expended.
@extie-dasilva, I must that I love the way you have the analyzed the state of job, not only in a capitalist economy, but this is almost true with the socialist and mixed economy.
