graphene sandboxes Google services so they don't run as root on your device. I haven't encountered an app I can't get running on graphene yet and having Google play installed as non root is a far sight better than stock.
my biggest problem with lineage was compatibility with banking apps so I reluctantly switched but graphene is a solid choice in operating system for privacy and security.
so that if it escalates there is a trail of information to bring to hr. especially if this person has been around the company longer.
