The 5 2nd most important rules in the railroad industry (second only to safety) that you'll never find in the General Code of Operating Rules, Airbrakes and Train Handling manuals or railroads Timetable/Special Instructions are as follows:
Rule number 1: Don't sh-- where you eat
Rule number 2: ALWAYS CYA
Rule number 3: Careful of the toes you step on today, they may be in the boots that kick you in the butt tomorrow
Rule number 4: ALWAYS justify your job
Rule number 5: If you screw up, MAN UP!! Nobody is perfect and occasionally, mistakes happen. Avoidable almost always, but they happen none the less. But if you take your hat in your hand and go before "the man" and cop to your mistake and ask for forgiveness, you're far more likely to keep your job and receive forgiveness. If you lie, deny and demand proof, chances are almost absolute that management already knows what happened and how and you're done.
