I worked jobs from pounding in by hand railway secondary lines to installing solar panels. If I couldn't get along on the crew, I left. I seen many people get more or less ran off a crew but coworkers because they were being shits. That is the reality of working with people and getting along with those you work for.

This applies to Western countries. Three is definately a greater level of desperation in developing nations where there is far less functional businesses to create jobs. Then yes you can be treated pretty bad.
