To succeed on this claim, [plaintiff] must prove each of the following elements by a preponderance of the evidence:
Second, that the jobs are performed under similar working conditions; and
Third, that [plaintiff] was paid a lower wage than the [male/female] workers in jobs that require substantially equal skill, effort and responsibility as [plaintiff]’s job and that are performed under similar working conditions.
In deciding whether the jobs require substantially equal “skill,” you should consider such factors as the level of education, experience, training and ability necessary to meet the performance requirements of the respective jobs.
In deciding whether the jobs require substantially equal “effort,” you should consider the amount of physical and mental exertion needed for the performance of the respective jobs. Duties that result in mental or physical fatigue and emotional stress, or factors that alleviate fatigue and stress, should be weighed together in assessing the relative effort involved. It may be that jobs require equal effort in their performance even though the effort is exerted in different ways on the jobs; but jobs do not entail equal effort, even though they involve most of the same routine duties, if one job requires other additional tasks that consume a significant amount of extra time and attention or extra exertion.
In deciding whether the jobs involve substantially equal “responsibility,” you should consider the degree of accountability involved in the performance of the work. You should take into consideration such things as the level of authority delegated to the respective employees to direct or supervise the work of others or to represent the employer in dealing with customers or suppliers; the consequences of inadequate or improper performance of the work in terms of possible damage to valuable equipment or possible loss of business or productivity; and the possibility of incurring legal liability to third parties.
In deciding whether jobs are performed under similar working conditions, the test is whether the working conditions are “similar”; they need not be substantially equal. In deciding whether relative working conditions are similar, you should consider the physical surroundings or the environment in which the work is performed, including the elements to which employees may be exposed. You should also consider any hazards of the work including the frequency and severity of any risks of injury.
5{If you find that [plaintiff] has proven [his/her] claim, you will then consider [defendant]’s defense. [Defendant] contends that the differential in pay between the jobs was the result of a bona fide [seniority system; merit system; system which measures earnings by quantity or quality of production; or describe factor other than sex6 upon which the defendant relies]. On this defense, [defendant] has the burden of proof by a preponderance of the evidence. If you find that [defendant] has met this burden, then your verdict will be for [defendant].}
