Usually about 13 hours. I leave for a 1000-2200 shift at 0930, get to work at 0945. Check stock on the squad and get ready for the day. Usually get called back to base at 2145, end of day restock and squad break down, BS with our dispatcher for a while and I'm usually out by 2215 and home at around 2230. Sometimes I get home a little later and sometimes a little earlier. I worked an eight hour shift this past Friday and it felt really weird to only work eight hours.
