If my employer proposes arbitration (vs judical system) should I 'opt out'?

I have been employed by a National company for over 25 yrs. They are now asking us (as managers) to decide if we agree any future disputes will be handled by litigation, otherwise we elect to ‘opt out’ and retain the right to any future disputes to be settles within the US legal system. My employer does apply for many patents and they routinely pay fees for employees ideas that lead to patents. I am not in a position that I foresee any future disputes I have would not to be related to patents, more so human resources types of issues. Please, knowledgeable jellies, can I gain from your advice on the pros and cons of litigation vs the US legal system?
