If your employer expects you to access corporate resources or be available to respond / on-call out of hours, then they should issue you a corporate device to do so.
Really, Work Profiles and a stipend are the way to go. I don't give a damn what you have on your phone - couldn't access it if I did, which I don't. If you opt to get your work email, cool - I'd like you to use the work profile, we can and would like to help you set it up. We'd really like you to have our emergency notification app due to our industry. It'll help in an active shooter situation. But you don't have to.
