The correct option is C No job security
It is now a well-known fact that casual labourers work in conditions that most others would find utterly unacceptable. Besides, they are granted no benefits or insurance cover. However, they often make it a point not to raise issues with their employers, given that they are never guaranteed job security. As high as their aspirations might be, the fate of employment rests solely in the hands of the employer who may readily choose to replace the individual. The labourer would then lose his/her source of income.
