I was working the Foul Line FLM/CIC position. I noted; when I sat down; that the ORD arrivals were continuously exiting their pre-assigned descent airspace; used for arrival into ORD. This was placing the aircraft into Sector 3's airspace. It is important to note; that Rockford Approach feeds Sector 3; at 5;000 [feet] directly towards the ORD finals; and Sector 3 only has roughly 10 miles to descend out of the way. I asked Sector 3 if anyone on arrival had pointed out these aircraft. They said no. Later; when arrival had too many aircraft; they did point out 3 aircraft from the SW descending below the south final; into Sector 3 airspace; but besides these three cases; roughly 20 or more aircraft entered Sector 3 airspace without coordination. On multiple occasions; I addressed the situation with the 20 (Front line FLM/CIC) and the [Manager] was standing there during the conversation. Not only did the 1W1 position continue to violate the airspace; the 1F1; started to as well at 4;000 [feet]; taking two of the three available altitudes from Sector 3. This occurred for well over an hour. When I asked [Front Line Manager; FLM] about it; [the FLM] insisted the fixes were already slowed. I suggested they hold; as they were not staying in their airspace. As predicted; the 1W1 left the airspace again; while we awaited RFD to ship Aircraft Y; so we could descend. We didn't lose separation; however; it was imminent. The aircraft were head on at 5;000 [feet] with 10 miles or less between them; on two separate frequencies.We have procedures and airspace to accommodate for this. The 1W1 has the ability to turn on the final at 6;000 [feet]; and they own 6;000 [feet] to the boundary but chose never to use it. The FLM never assisted in reducing the traffic allowing the vector positions to stay at their turn on points. This isn't the first time I have witnessed and reported arrival spending more than an hour out of their airspace; without coordination; and without management doing anything about it. I have filed reports about this before. Time to correct this problem. Please share with whomever you wish.
C90 TRACON Controller In Charge reported numerous airspace violations due to others not pointing out aircraft correctly.
