Suppose exactly the day after a paycheck they decide to stop paying me. 15 days later I don't get a check, and 7 days later I stop working due to the paycheck issue not being fixed (maybe I gave them the benefit of the doubt, it's a minor snafu). At the worst, I'm out 22 days of pay, assuming their high priced lawyer lets them get away with this (highly unlikely).
I don't need insurance for low cost, low probability events.
