Do they get paid more if the company does better? Yes, this is the only reason to do more than asked from your job description. Otherwise you are putting money and decision making power into the hands of people who did not earn it. Only bad things come from uncompensated work; A bitter employee, angry co-workers, and a misunderstanding of where profit is coming from by the business analysts can ultimately hurt business. If someone is making the company more successful pay them more otherwise tell them to slow down. If you are of the later mindset then YOU are not benefiting the company.
