Your hands are tied until the children are either placed in danger OR you get to trial.
If you go to trial and are allowed to call witnesses, you CAN subpoena the teachers/principal if you need to.
You need to learn to live without the CS. Obviously you can't count on her. She's simply going to incur the debt,though since you are with FRO, she can't sit around indefinitely. Eventually they will suspend her license and start taking other action. (will take MONTHS, but it will happen)
Until then play it by the letter of the court order. Speak with the school and indicate that unless they are informed in writing of the absence, you want a phone call and to have it noted on the student record.
If the child misses too much school, then start pushing for someone to investigate the truancy, and keep pressure on CAS. They are bullshitting you by the way. A court order has NOTHING to do with them being involved or not. If it's a protection issue, then they can get involved. So far, NOTHING you've said is a protection issue.
Hubby callls employer to inquire about what the heck is going on...Finds out she was temporarily filling a position for an employee who came back to work, they have her listed for casual shifts...but have no casual shifts available
THAT is a huge breach of privacy and she CAN use that against your hubby. Stop giving her ammunition, you are in a good spot and you are handing her things to use against you if she's got even half a brain. All you are doing with that is muddying the waters. You have a court order, you are filed with FRO, it WILL catch up with her.
The wheels of justice are turning (they're slow, it sucks, but it is what is it) and you are sitting in a pretty good spot to secure a custody change.
Her employer could get in a LOT of trouble for releasing that kind of information without her permission.
