Answer:
A) Changing his inputs
Explanation:
First, we have established that Doug thinks that the payment received as an employee of McDowell Instruments is not fair enough considering his level of input. This is according to the theory of equity, where it is theorized that the motivation of individuals to get work done is usually based on having a sense of fairnes sin their interactions.
As a result of this theory, Doug sees his interaction with the company as unfair based on wages received. By taking more break time therefore, he rationalizes that he can reduce his input time to match the level of payment he receives from the organisation and as such his input to McDowell Instrument should match the pay he recieves.
