Yeah, call your manager, if you know they are off on vacation, then call the next manager or just call the station.
I prefer not to call the station because the managers are paid to deal with this, plus, some of our CSAs are bitches that will make snarky remarks because "THEY COME IN SICK ALL THE TIME".
Look, sitting on your ass dealing with traces and being on the phone is a little different than dodging traffic and driving all day.
Plus, if you are actually sick, banging in prevents the rest of the station coming down with whatever you have, so it's a win-win. It just sucks that being sick is so demonized by most because most people bang in 'sick' when they just want the day off... but that's another discussion.
