Employees never have 2000 hours worth of labor at risk; they (usually) get paid twice a month, so they only ever have about 80-100 hours worth of wages at risk at any given moment.
If their employment ends, they no longer have the income they used to, but they have 40 more hours a week to use. Most will try to find another employer that will give them money for their time, some will start their own business, and others will retire and use the extra time for leisure.
Investing your time in earning wages is one of the least risky investments you can make; on the other hand, returns on investment tend to be inversely correlated with risk.
