In a capitalistic society where companies hold an exceeding amount of power over not just their workers but the world in general, it is no wonder that those companies will try to push the limits of what they can get away with. Furthermore, they will try to wring every ounce of energy and work out of their employees. This can lead to some awful working conditions, as well as some downright illegal ones as well. If proven, the affected employees deserve compensation.
Being terminated from a job, whether it was a firing or as part of lay offs, is never fun. Anyone in that situation is going to be upset and have thoughts centered on whether they were treated fairly or not. Some of these people have legitimate reasons to feel aggrieved.
