I note that if you build up four weeks of savings in at-will employment, then compared to four-weeks-notice, you have the same level of security and more time to dedicate to job hunting.<p>(For people living paycheck to paycheck, four weeks of savings might not be easy to accumulate. But those people can&#x27;t suddenly start spending more money if they get better job security. So there might be a compassionate argument, but the economic one doesn&#x27;t seem to hold.)
