Employment in this country is employment at will. That means either party--either the employer or the employee--can terminate it at any time, for any reason, without prior warning or notice, and without incurreing any liability (i.e. without being sued). Just as they could legally fire you if they chose and you'd have no recourse, so, too can you resign or quit at any time and not incur any liability. In this country, you can be fired or quit at any time.The only exception would be if you had a written employment contract in which your agreed to work for a set time (e.g. a one-year contract which has not expired) or provide certain minimum notice (e.g. 30 days). If you resign in violation of a contract, you can be sued for violating the contract.
