 b. Any of the employers will not work for the welfare of employees until he is forced to do so.

 c. This theory is based on the contention that a minimum standard of welfare is necessary for workers.

 d. The assumption on which the theory is based is that without compulsion, supervision and fear of punishment, no employer will provide even the barest minimum of welfare facilities for workers.

 e. This is based on the contention that a minimum standard of welfare is necessary for labourers.

 f. Here the assumption is that without policing, that is, without compulsion, employers do not provide even the minimum facilities for workers.
