And one worker on the board would change that? How? If the managers - whose duty is supposed to be knowing what's going on, that's literally what they are paid for - can't, how one person whose job is doing something else, could in addition to that gain adequate knowledge of what's going on that is impossible for others to gain? Especially in a company that has, say, a hundred of people? Best case they would know what's going in their corner of work, but in any company which doesn't fit in a single room that won't be representative of others. Unless you make that worker spend whole day on figuring what's going on, talking with all workers from all other rooms, systematizing and analyzing and processing this information to make conclusions - by which time, you just made him a manager.
