If you quit a part time job so you can collect unemployment due to the loss of your primary income and your part time employer does not inform you that you will lose your unemployment benefits?

The unemployment benefits in all states are intended as insurance for the "non-voluntary" loss of employment, i.e., layoff or RIFs [Reductions in Force]

That means, with a very few exceptions for extraordinary circumstances, that if a person VOLUNTARILY QUITS a job, then that individual IS NOT ELIGIBLE for unemployment benefits.

The employer paid, payroll based, "premium" money "paid" to the states is only barely enough to cover the operation of the unemployment system offices and staff, and IS NOT the same money benefit recipients receive.

The money in a weekly unemployment check is paid by the last employer who terminated the recipient

Also, in Texas [I am unaware of other states], self-employed individuals are not eligible for unemployment benefits. Ostensibly, the reason for this is that if the self-employed individual is "out of business," then how could he pay his own unemployment benefits!

Because of the last employer having to pay the weekly unemployment benefit checks, when a terminated individual files for benefits, the claim is forwarded to the employer who is allowed to challenge the claimant's eligibility to receive payment of the benefit.

If the employer claims, and can prove, that the employee voluntarily quit, OR was FIRED FOR CAUSE, then the employer can "kill" the claim, preventing the need to have to pay the benefits, and thus preventing the ex-employee from receiving any payment.
