I know what it is to look back at past and present co-worker experience. Now i've had limited work experience but here is some them...
A co-worker who needs to feel important so they will make you do things they can do themselves and have even been told by management as much. Then they had an absence at work and kept telling ppl that we would fall apart without them. Not only has the contrary happened but we've actually improved on it. Now they are refreshingly speechless. Same employee would cc: management on every single detail of their movements...apparently they just wanted to remind the forces that be that they were ACTUALLY working.
Another employee would actually send, when we had them, our student assistants to get them lunch. Not only did they not have cash but would give them their ATM card and pin. And then they'd change the pin just in case. They would also be too lazy to go to the bathroom and hold onto it and then complain they haven't gone all day.
I could go on.......the stupdity just is never ending...
