Narrative:
ZAU was providing headings and s-turns for spacing into chicago. We were handed off to approach with a 360 degree heading at 11000 ft. Captain X contacted approach and we were advised expect vectors, expect runway 27L. Captain X then left the frequency to contact inbound operations. Approach then contacted me and asked why we were not slowing. I advised we had not been given a speed reduction. Approach replied that we had been instructed to descend to 7000 ft and that would require slowing. I then advised that we had not been given an altitude change, but would begin descending to 7000 ft. Approach then commented that he would check the tapes on that and 'descend immediately to 7000 ft.' I complied and when the captain returned to frequency, I asked if he heard the atl change. He agreed that one had not been assigned and he had not read one back.

Title: C90 APCH CTLR QUERIES AN EMJ COMMUTER CREW AS TO WHY THEY HAVE NOT COMPLIED WITH A CLRNC DOWN TO 7000 FT FROM THEIR CURRENT 11000 FT ON VECTORS TO RWY 27 AT ORD, IL.
Narrative: ZAU WAS PROVIDING HDGS AND S-TURNS FOR SPACING INTO CHICAGO. WE WERE HANDED OFF TO APCH WITH A 360 DEG HDG AT 11000 FT. CAPT X CONTACTED APCH AND WE WERE ADVISED EXPECT VECTORS, EXPECT RWY 27L. CAPT X THEN LEFT THE FREQ TO CONTACT INBOUND OPS. APCH THEN CONTACTED ME AND ASKED WHY WE WERE NOT SLOWING. I ADVISED WE HAD NOT BEEN GIVEN A SPD REDUCTION. APCH REPLIED THAT WE HAD BEEN INSTRUCTED TO DSND TO 7000 FT AND THAT WOULD REQUIRE SLOWING. I THEN ADVISED THAT WE HAD NOT BEEN GIVEN AN ALT CHANGE, BUT WOULD BEGIN DSNDING TO 7000 FT. APCH THEN COMMENTED THAT HE WOULD CHK THE TAPES ON THAT AND 'DSND IMMEDIATELY TO 7000 FT.' I COMPLIED AND WHEN THE CAPT RETURNED TO FREQ, I ASKED IF HE HEARD THE ATL CHANGE. HE AGREED THAT ONE HAD NOT BEEN ASSIGNED AND HE HAD NOT READ ONE BACK.
