The "theft" in question was an overcharge. Even if the cashier did not pocket the money, the company still considers this employee theft.

Also, is it possible to litigate w/o an attorney? To obtain evidence through discovery without enlisting a lawyer? Finally, is there a government agency that can help me, or a pro bono organization? I haven't had much luck in my searching thus far, and being newly unemployed limits my ability to hire a pro.

Thanks again for your help.
