Employers can usually fire employees for any reason. However, there are exceptions to the at will rule. You have the right to see your personnel file. An employer must allow the employee to inspect the file within a reasonable amount of time after the employee asks to see it. It is also important to know that you can add your own documents to your personnel file, which may be a good idea if you disagree with some of the information in the file.
Different laws provide similar rights to most public employees.
You may be entitled to penalty wages if your final wages are late. If you quit, and gave your employer 72 hours of notice, you are entitled on your last day to all wages due. If your employer willfully refuses to pay you within these time limits, your employer is subject to penalties for each day that your wages are late, for up to 30 days. Use it or lose it vacation policies are illegal. You do not forfeit unused vacation when your employment ends.
