So, who does this kind of work? Why do people do this kind of work that others do not want to do?
People do not want to do jobs of sweepers, dish washers, sewage cleaners, white washers, etc. People do not opt for these jobs because after getting educated, they get other options of employment. They want to earn more and think these activities are neither interesting nor of their status.
This kind of work is done by:
(i) Poor people
(ii) People belonging to a particular community in which their elders also have done the same work.
(iii) People who did not get chance to do other jobs
Some people do this kind of work as either they do not have the money to study or even after getting educated they cannot not manage to get other jobs.
