I have seen the “floaters” but it’s rare. What is worse are the occasional people (and some companies have lots more of this than others) that are a net negative impact to the productivity. There are different reasons but sometimes they believe that their work adds value but in the end it’s really just creating inefficiencies (like creating processes for process sake, work about work etc). That’s how large companies with everything going for them can easily start loosing their edge - when there’s more “no” people than “yes” people!
