work evaluation having to rate co-wokers ?

[gorie]

every year at work we get this stupid "self evaluation" sheet we have to fill out, "what do you do" , "what do you enjoy about working here" , "what are new skills you've learned" blah blah. and a sheet to rate yourself on stupid things like attendance, efficiency, accuracy, blah blah, same stupid questions every year with the same stupid answers every year.

anyway - so this year we have a sheet added , asking us to rate our co-workers.
it lists everyones name, and there are about 10 different things to rate them on , ona scale of 1 - 10. like how well they do at their job, if they are trustworthy, etc.
i didn't read all of them , i just glanced at it and thought "wtf" as i was leaving for lunch, and now i'm kind of annoyed about the idea of having to rate other people.

is this weird or what ? it's stupid enough having to rate myself every year on this stupid thing.
i definitely don't feel right being asked to rate other people.
is this normal and common for the boss to ask employees to rate the people we work with ? am i weird for being somewhat offended by it and not wanting to do it ?
