On a typical day I'd arrive to the designated site and wait for the truck, then load/unload cargo according to the supervisor instructions.
I learned how to properly handle big items and how to secure them on a truck.
Supervisors and other casual workers are very friendly. Good initiative and attention is welcomed.
The hardest part is to move and manoeuvre big cumbersome pieces harder to take good hold of.
Most enjoyable part is the teamwork dynamic and companionship.
