If you have the option to talk to a manager either before your work shift begins or after your work shift ends on a particular day, you might want to consider doing that. Otherwise, writing a letter to a company manager and passing the letter along to the manger might be something to think about doing. As one of the previous posters mentioned, looking for another job where your coworkers might be more respectful toward you might be a good idea, but I'd recommend doing as much as you can to try to get your coworkers to treat you more respectfully before quitting your job. And if you do eventually decide that leaving your current job might be the best thing to do, I'd advise looking for another job while you're still working for your current employer, if that would be at all possible for you. As I understand it, companies are more likely to hire somebody who's currently employed than they are to hire somebody who's recently stopped working somewhere else, so I think that looking for a different job while you're still working at your current job would be the best thing to do if you do decide that staying at your current job isn't what would be best for you.
