I am in IT and have been working on line from home for about 3 years. I can not drive, and have trouble standing. I am 68 years old. My company has now asked me to come in and work from the office. It is a one and a half hour drive each way, and my legs can not handle the drive. Can they dismiss me for refusing to come into the office to work?

They can dismiss you, but would owe you severance. For you, that would easily be the equivalent of 6 months pay, and potentially more. In light of the fact that there are medical reasons preventing you from going to the office, this may be a human rights matter as well. I recommend that you provide your employer with a doctor's note that confirms that you cannot come to the office for medical reasons. If they insist or if you are let go, please call me right away.
