It does and it doesn't. Most wired ethernet isn't on shared media, so it doesn't need/use csma/cd... But wireless is based on ethernet and uses csma/cd (wifi) presumably

I wonder if we were still using hubs back then. We bought a bunch of Cabletron switches around that time

Wireless uses csma/CA, IIRC. It avoids collisions rather than detecting and responding.
