Is it better to resign in leiu of termination?

Letting your employer fire you, as opposed to voluntarily resigning, better protects your rights to later assert a wrongful termination claim and to obtain unemployment benefits.  If you resign, you may be disqualified for unemployment and, if you later assert a wrongful termination claim, you will be faced with the additional burden of proving that either you would have been fired anyway or in certain types of harassment claims, that no reasonable person would have remained in that position.
