The above statement assumes a definition of work as the totality of prescribed and discretionary activities that a person does in discharging the responsibilities he has contracted to undertake in order to earn his living. Moreover, concealed within the statement-in the prescription for measuring level of work-is the notion that what is experienced as one’s level of work has only to do with the use of discretion and judg ment, and has nothing whatever to do with the prescribed content of one’s work. These definitions of work and of level of work have been tacitly used in the preceding part of the
book. They can no longer simply be taken for granted. Before proceeding further, we must examine them, discover what their implications might be, and see whether any justification can be found for their use.
