There are many times during the course of a person's employment when, for reasons not related to age, they are no longer fully able to perform their services. I'll use the example of somebody who is a bus driver. Of course, you'd have to have good vision. Over the course of time, somebody might lose their vision, and although they would no longer be qualified, that would have nothing to do with how old they were but would be because of that. You're not able to accommodate somebody who is sightless being a bus driver, to put it very simply.
Many of the cases that do come before us are situations in which an employer says an employee is no longer qualified. I'm talking about cases other than the mandatory retirement ones in which they would then have independent medical assessments or that kind of thing. We heard earlier that in the airline industry, testing and so on is done frequently. At the commission we recognize that especially in safety-sensitive positions there is testing that can rightfully be administered. I'll use a mandatory drug and alcohol testing policy, for example. For safety-sensitive positions it is certainly permissible to do that.
