Redirecting the emails is crazy. I would assume, as an employee of any company, that they can monitor emails to corporate email accounts but outright redirecting emails is something I've never heard of
If CEO came to me and said "we need to archive all email to or from this recipient", the only unusual part of that ask would be the person requesting it.
We have The Work Number but no way to reasonably implement your suggestion. We’re cogs, just toast.
