Pretty sure that's a non-starter for anyone who needs to use their phone for work, which is more people than you would think now that so many office workers are remote.
Great, if a work phone is required by a company, let the company provide it and leave that one alone. Do you have to supply your own work computers or other equipment "required" to do the job as well, outside of contract work?
Unfortunately that assumes the employer will provide the phone rather than going "this guy can't do his job because his phone is rooted?" and hiring someone else. Or that the employer knows what rooting even is.
Most companies ask you to install work profiles and such only after your sign on. It would be exceedingly petty of them to fire you for something like that, especially at a tech company that will definitely have the money to provide ~$300 work phones
I run GrapheneOS on my Pixel 4a, unrooted, bootloader locked. However this avenue prevents the use of Google Play Services (which partially or completely eliminates functionality from many proprietary apps on the Play Store) or MicroG. This isn't a problem for me personally.
If you're a tinkerer it's pretty easy to bypass - the main method of rooting currently is Magisk, which also includes a very powerful self-hiding mechanism, able to bypass SafetyNet and most other root detection methods.
