Check your states requirements. Here, again, I say, HERE, you have to be laid off for at least a week. That first week counts as a "waiting" week. After that, you can file for all or partial weeks.
Yes, be sure to get your name filed immediately if your state is such. Get that waiting week outta the way.
And here, yes, HERE, if you're laid off from your specified job classification, you DO NOT have to take another position, especially if it pays less.
Years ago, while in construction, we were laid off every winter because of frozen ground. Collected unemployment. Boss fought it saying he offered me a job in the building, mechanicing, which he did. Took it to arbitration. Panel (state unemployment panel) agreed with me...said I didn't have to take anything below my pay scale or any other classification job for which I was not hired.
