The company faced the problem of mass absenteeism. Is it desirable to recruit workers from the same community?

In general it is a bad management policy to recruit or not to recruit workers based on criteria like their community, caste, race, or religion. In many countries it is also illegal to discriminate people for employment in the basis of such consideration.

The question mentions about problem of mass customization, and suggests that the problem may be solved by some form of discrimination based on community. There is no further data provided to establish validity or otherwise of such assumptions relating the incidence of mass absenteeism to membership to a particular community.

It will be appropriate to try to find a solution to the problem of absenteeism without understanding the cause of absenteeism. There is no data available to establish such causes. However, it would be wrong to assume the source of problem being membership of a particular community, just because of high incidence of absenteeism from that community. The problem of absenteeism is generally related to low employee morale: and the low morale could be the result of insensitivity of the management towards the culture and some specific community related issues faced by the community. Usually, the problem of high absenteeism and low morale is solved by greater understanding and support for the feelings of the employee, rather than by maligning the entire community.
