Not always and I will argue not even most of the time. Working in a nursery (ag not humans) is hot and dirty and there is nothing you (as proprietor) can do to change that. Washing dishes is going to get your employees' hands wet and soggy. Changing sheets is going to put your employees in contact with many undesirable stuffs.

If hindsight is 20-20, why is it so often ignored?
Think even a "hot and dirty" or hand-wrinkling job can be much more enjoyable if you have a decent salary, job security, and managers and clients that don't treat you like subhuman shit but, rather, as a human being worthy of a basic level of respect. Ofc this is also true of jobs that aren't so hot and dirty and base.
