You Jack System

Also known as the “Fuck You Jack System” where a person leaves behind a mess, does a half arsed job or just blatantly doesn’t give a fuck because they don’t care about the state of the job, task or place they are working because it will be someone else’s problem when they are gone.

Basically another way to call out people for being lazy flogs.
Sparky 1 - Jeez, cleaning these cable clippings will take forever…
Sparky 2 - Nah mate hasn’t anyone told you we work on the You Jack System!!!

New worker walks into communal kitchen and finds person has used and not replaced any of the paper towel, milk and left dirty dishes behind… thinks to themselves jeez these flogs work on the You Jack System here.
