I think your employer is stupid if you have a skill that they ignore.
It is hard to balance your left and right brain out. There aren't many who bridge the gap and do both programming and art.
And that type of person can really be beneficial to a team.
Most of the people in HR departments wouldn't know anything about that though since they only do what they are told.
And from what I gather, they are told to seek highly specialized people with no knowledge of other fields.
Valve is one of the few companies that recognized multiple skills as a trait of value.
