Can you elaborate? how was the selection process done?
Are you entitiled to have access to the proceedure for selection?
There are many reasons why a particular person is selected,so maybe think about why you would have been and see if its justified.
I would think most companys would look at the persons work record and how they contruibute,if they are willing and not obstructive to work practices etc..
For example if a HR manager has two people to choose from one is always moaning ,not happy to comply with work practice changes ,millitant etc and the other worker is happy to get on with it ,is not causing problems or obstructing every change then I would imagine the company would want the second person..
Some people who are selected are rather afronted by the fact that they have been chosen and never stop to think why ..
