When I worked at Boeing, I heard a fun fact about how 20% of the people working do 80% of the actual work while 80% sit and do nothing. They just sit there and collect a paycheck. They do not pay attention to what's going on around them. Then they wonder why they don't ever move up.
Other people have an issue of being very good at what they do and get so good at doing something one way that they have an inability to change or adapt to the changing times. If it is anything out of the "norm" they cannot change.
Other people have this incredible ability to pass the blame onto other people while not doing their full job. It can be so frustrating.
