Adam Catlin has worked as a Wal-Mart greeter for ten years. Then his job description changed, and he'll soon be required to agree to a new set of physical demands he's not capable of. Now he fears he'll lose his job.
If he has served as a greeter for a decade, it means that he qualifies for the job. There is no reason to change the requirements and require him to stand for his entire 8-hour shift. Standing for eight hours straight is hard enough for the fully abled!
Please don't force Catlin to give up his job just because of his physical condition.
