A better interpretation of unemployment insurance is you are no longer able to work through no fault of your own. That varies a little between states, but most places you are able to quit for cause and collect UI. A few examples is if your pay significantly drops, or your job duties change significantly, or your place of employment moves to an unreasonable commute. The flip is also true, you may be ineligible for UI if you're fired for cause. Quitting vs resigning isn't a direct correlation to collecting UI, though they often rhyme for general cases.
