You were working too much and you made everybody else look bad. Also, they didn't have budget for a raise so they gave you a poor review. I worked at a company like that. You see, if they give you a raise then the budget must grow. This is the job of the manager. But as he isn't doing his job, budget is not growing. So bad reviews all around. This is when top manager think they are so smart and come up with these rules, and then middle managers bend the rules.
