Thanks for the feedback, cbg. I think I understand what you're saying. What's still unclear is the responsibility of a prior employer when a current employer lays someone off. Let's say someone works concurrently for Company A and Company B for 5 years. A pays 80% of the person's income, B pays 20%. The person voluntarily quits A. There is no dispute that it was voluntary. Three months after quitting A, the person is layed off from B.
The person files for unemployment and they establish a base period which includes income from both A and B. According to everything I've read on the EDD website, only the last employer (B) is contacted with the Notice of Claim Filed (DE1011CZ), etc. Is this correct? So even though the majority of the income was earned from A, from which the person voluntarily quit, the person will still receive benefits (for the sake of argument, let's assume that the person qualifies for benefits due to being layed off from B) based on the highest quarter in his/her base period, which includes income from A. And is it further correct that A will not even be contacted?
Sorry for the long post. I guess my question could have been summed up like this: Is only the last employer contacted when someone files an unemployment claim, even though a person had multiple employers during a relevant base period? Furthermore, is only the last employer subject to having funds taken from the reserve account to pay for the benefits, and only the last employer subject to having their UI rates increase?
Thank you so much to anyone who made it through this post. Any additional help will be greatly appreciated.
