that means they can't collect un employment benefits

Not always. At least in this state the employer will receive a form on
which they can state (inter alia) that the employee resigned in which
case benefits may be denied. However, if the employer doesn't return
the form or fails to contest an appeal from the employee, benefits will
still be paid. It is not unknown for companies to agree not to fight
unemployment claims in a settlement agreement.
