What is the impact of a decision made on the basis of cost versus cost on the distribution of overtime hours?

50 In establishing whether or not a particular overtime allocation made on the basis of cost (ie. time and one-half v. double time) caused an inequitability in the distribution of overtime over the course of a quarter, one cannot simply compare the total points or hours accumulated by each officer at the end of each quarter. Nor can one establish this by simply comparing the quarterly totals of the officer who claims to have been bypassed in comparison to the officer who was allocated the overtime. Since the number of overtime hours worked will largely be determined or influenced by the number of shifts for which an employee indicates his or her availability, such a simplistic comparison does not necessarily lead to a proper result. It may be that an officer’s low totals at the end of a particular quarter are accounted for by the fact that he or she indicated availability on only a few occasions rather than by the fact that they were bypassed on one occasion because the employer would have had to have paid them double time.
