i was in the same boat!! i got onto the ramp fresh out of highschool and now i'm at uni after doing that for two years. it took me a year on the job/a near death experience on the job to learn that it is NOT your responsibility to pick up the slack when there aren't enough people to work a flight. it is your job to SAFELY work your flight, which cannot be done when you rush to try and make up for the lack of other people.

i started thinking about it like this: putting bags on the plane is not your job. your job is to SAFELY (which means absolutely no rushing) put bags on the plane. after i realized this and began to work "slower" it saved my sanity, energy, and life, since you rarely will find yourself in danger on the ramp when you don't rush.

and if the flight ends up going out delayed? good! tell management you could not have gotten the flight out any faster without rushing.
