First, I am very sorry for your friend's circumstances. Leaving an abuser is incredibly difficult and very dangerous. She needs the support of everyone in her life- including her family and friends.
Given the facts you've provided, your friend should be able to protect herself without having to leave her job. Her employer should have a copy of all restraining orders and she should call the police anytime he is in violation of those orders. She might also want to notify her employer of her concerns and fears and they may have some additional protections available to her- like having someone walk her to her car everyday or on-site security have notice of the potential presence of her abuser on the premises.
Her employer, landlord, children's school, family,etc. should all have copies of her restraining orders. Any contact is likely a violation. If he's following her or showing up at her home, she needs to call the police. If he is showing up at her work, she needs to call the police. If he is making threats of violence, she needs to call the police. She should also continue to avoid contact with him. If he is stalking her, any attention of any kind will likely encourage his behavior.
The bottom line is that she needs to take advantage of the protections she currently has. She may also want to consider changing and reinforcing her locks, and having a safety plan just in case his behaviors escalate. Good luck.
Understand your friend's concerns and thought of a temporary change of location. That never works. These guys always find their target. Better to stay where she is around people who know her.
Advice? Do exactly what my colleague has suggested. Plus call the probation officer and report the violations. Also call victim witness.

I agree with my colleagues moving is not a solution. Report every violation, make sure everyone has a copy of the order. Look for domestic violence help at your local legal aid. Fresno has the Majoree Mason Center and Central California Legal Services. Look for agencies such as this in your county.
