Unless you think you might be promoted or the company has a very good benefits, I would look for other jobs in my spare time. I am only happy at work when my supervisor is focussed on the mission verses just coming in for a paycheck or trying to get ahead at other peoples expense. In the meantime, try to not think about it when you are not at work. Though I know this is better said than done. Being conscientious is a good quality. That store has a big problem if it doesn't find this mindset valuable.
