I think there is a large difference between number of employees who have worked at a company that had has layoffs, and number of times they were laid off.

Assuming your experience is representative of every company (I don't think it is) then every company lays off 10% of their workforce every 2 years.

Assume a random distribution (I don't think this is true) that means the average worker get laid off once every twenty years. So you're looking at 2 lay offs a career. Savings should be sufficient for this. Policies or agreements like this just make good hirs cheaper, and bad hires more expensive.
