The usual way companies handle this is to set the actual layoff date as 60 days from when the email goes out. If you hear about a mass layoff including two months of salary for everyone affected, that’s what’s going on. Typically system access is revoked but the paychecks keep coming as usual and vacation keeps accruing, because you’ve got that extra two months of “employment.” The company also gets the benefit of being able to call you back in if it turns out there was something vital you were doing that never got documented.

This, the company stays compliant with all the regulations but they don’t have to worry about disaffected employees during those 60 days.
