We have an employee who is seriously overweight. This employee was overweight when he was hired, so I can honestly say our Company does not discriminate against such things. However, since his employment here, he has added quite a bit more weight. He is well liked by his fellow employees and supervisors. We are just extremely concerned about his health. He is a delivery Driver and now cannot fit in most of our vehicles. We have had numerous customers call and ask that he not deliver to thier facilities, as they are concerned something may happen, as he is consistently out-of-breath by the time he finishes the delivery. We donot want to term this employee as he may feel he is being discriminated against. Any suggestions?
