DS was on probation and had a PO that I was very impressed with. She was an ex-cop and I wouldn't even want to pi$$ her off even on a good day! :-)
She called me when there was an upcoming court date or making arrangements for his residential tx. And she only talked to DS when she wanted to give him an 'attitude adjustment'! But no, she did not call every once in a while, because part of his probation involved being supervised by home and school. Here in IA, that type of contact is apparently a given for minors, unless they are in residential tx (and then they are supervised 24/7 anyway). It's very different than an adult, who normally doesn't have to answer to anyone. That's why PO's stay in closer touch with adults. At least that's been my take on the situation.
But at least she would return my calls within a day or so if I left her a message. If you can go over this guy's head to his supervisor, I would certainly ask what his specific responsibilties are to you and your DD. Make sure when you do call him, you detail in your message what you are calling about and when you expect to hear back from him. If you just leave a message that you want him to call you, he might very well take his time.............if you're in a metro area, I can about guarantee you the caseloads of PO's, even for juveniles, is pretty high. We live in a rural area, but DS's PO work two counties and I know her caseload was high. It's no excuse, but I understand it.
