How old is your boss?

[cannongal]

The woman is "28" years old, so my friend is somewhat put off being supervised by someone half her age, and no experience in the specialized job.

Is she wrong to be upset?

That really sucks for your friend. In essence, she is going to have to 'train' her own boss to do the specialized job.

If your friend has been working there for over 30 years, maybe the company thinks she's going to retire soon, too?
