I strongly suggest you be extremely careful about keeping your work and personal information completely separated. Remember your employer basically owns the rights to anything and everything you put on their telephone.

You should very strongly consider only using Apple Music (and everything else personal) only on your personal iPhone.

Only if both iPhone uses the same Apple ID & password.
