On the phone, simply sign the AppleID out of iCloud, FaceTime, messaging and the Music, App and Book stores.
If you want to, you can create a work ID for your work phone.
When changing to the new ID, there may be some data loss, but you can minimize it. If syncing photos with iCloud, ensure Optimization is turned off in Settings/Your Name/iCloud/Photos and/or in Photos/Preferences/iCloud.
