SOP
A large US retail big box company has had a similar policy for years.
An employee (or maybe 100 employees) are told "You must reapply for your own job, or perhaps apply for another available vacancy. If you don't get either job.....severance!!"
This is a company which has C-level staff who regularly roll out the badge of pride that "Our company has never had layoffs".
In my case, they did me a favour.......I resigned and immediately found a better paid job in a much healthier company.....something I should have done much earlier in my "career" in retail!!
Fantastic and unbelievable......ten years in post with regular positive appraisals....."reapply for your own job"!!!......with every expectation that you won't get the job!!!
