I have to disagree with your opinion on voluntary layoffs.
Here in the UK an employer has to inform the government and go through a mandatory redundancy process when laying off more than a given number of employees (I think it's 100 off the top of my head). At my last role I was put at risk of redundancy and went through the process. One of the first steps of that process was offering voluntary redundancy which had a higher redundancy package than if you received compulsory redundancy.
If someone was considering leaving, or was close to retirement leaving voluntarily gave them the opportunity to leave early and with a nice payout. Or if you had skills high in demand it gave you the opportunity to get a lump sum and walk into a new job.
This significantly reduced the need for the company to make compulsory redundancies.
