This espescially goes for supervisors that don't know you or haven't worked with you who's rating you but if they dont want you to get a raise or change departments they will list off whatever generic reason they can.
Mostly these are points that don't require actual documentation or events in time that can be disproved. When asked they avoid the question or say “it's been overall noticed in general”
On their lists on reasons you can't be disputed they may say
1. You don't work well with others/Work as a team
2. You don't have enough experience/picked up things fast enough
3. Unprofessional behavior
4. Failure to improve job performance (could be disproved depending on field of work you're in)
5. Personal Problems affect work performance
6. Doesnt bring new ideas/Creativity issues
7. Needs communication improvement with customers and staff
8. Managing time more effectively
9. Anything else that can be said without evidence/a way to pin where it's coming from/who said it
A coworker of mine just experienced this, he got promoted to a lead then a month later applied to another department that was much more suited to his degree and he'd get more experience from. They told him he “Doesn't work well with others” despite both supervisors not ever working with him. Everyone on our crew disagreed with that statement. We even go out fairly often as a crew to trivia nights at local restaurants/bars. The truth is they didn't want to lose a lead and he'd be harder to replace than it would be for them to fill that position. It brings down morale if you tell employees they can't progress any further but if you make them feel like they aren't good enough they may work even harder..
It's easy to let them tear your confidence down about these remarks but do not let them. They are designed so that they can apply to almost anyone. Often even if you have examples of times this didn't apply to you they will come up with some rebuttal of how you could improve. The decision is made before they let you know the outcome and often it doesn't have anything to do with you.
