If I don't know an answer to a question, I would either try to take it upon myself to research it and see if I could find the answer. If I cannot find the answer, then I would go to one of my fellow employees and see if they had the answer or be able to give me any kind of direction on the answer that we're looking for. And then once I got that answer, I would make sure to be proactive and get a hold of the person, call them back and let them know what the final answer is. Or let the fellow employee in the office know what the final answer is.
