"Hybrid" is just in office work with a fancy name. A company I worked for pushed heavy for RTO and said "Its part time Hybrid". But we already had 1+ days (at managers discretion) WFH a week before covid hit. Hybrid was In office Tuesday through Thursday with remote Monday and Friday. This was actually less flexible than 1 or maybe more as you need it WFH that we had it prior.
YMMV. two of the companies I worked at mid-post pandemic were truly hybrid when they opened back up. Some people never ever came in and a few came in everyday. Others still were very far away so it was never an option.
But I've also heard of old co-workers at later jobs where hybrid was just flowery words and really meant "mandatory remote time and mandatory office".
