I've made up my mind. If it happens again, I'm threatening to go to management. If she still disregards my wishes, I will go to management.
One more time and you'll only threaten?
Another time after that, then you'll go to management?
Well, she's already pegged you for a wuss.
Some day when she's confronted by management she's going to say that you allowed her to use her phone all that time and she had no idea it was a rule. Then you'll be gone and she'll have your job.
Report her NOW while you may still be able to salvage your job.
