the exact reason why I always preferred laborer jobs to office jobs, not many understood among my family and friends.
when i was a laborer, i noticed no one faked anything, we were all just ourselves. once i graduated to office jobs, thats when i noticed the fakers.
What a load of shit. I was also a labourer and there were guys who "forgot their wallet" when it was their turn to bring the coffee which we all looked forward to on the colder days. Then there were the guys who lost their license for a DUI and tried to hide it as long as they could while sponging rides from the others under the guise of card trouble, wife needs a car I'm getting a bike soon etc... Jesus. There was tons of false bravado and comparisons cars/bikes/tattoos and who slept with the most women. People are people; it's just that the games get headier in an office environment where belching and farting aren't legitimate comebacks anymore. Also, you'd probably get fired for whistling at each woman (or man) that happened by. I couldn't afford to waste my hard-earned money on a Harley and tattoos so I was forced into the office for a while (tech stuff - mostly sealants and paint) and finally settled into a production plant environment where there are people of all types and we get diversity training so we can all get along.
edit: Almost forgot, I also worked as a farmhand on a fruit farm (pay was heavily gov't subsidized). We weren't allowed to talk while pulling weeds and rocks from the field so head games were at an absolute minimum. You got a couple of warnings for talking and then they just sent you home.
guess i was just lucky then. it was construction, we all pulled out weight and got along great, and partied a lot outside of work.
my office gigs however.. many backstabbers there.
I think it's a different kind of disingenuousness. Laborers are boastful, prone to exaggeration, the proverbial fish that gets bigger with each retelling. The lies are designed to elevate ones self. In the office the lies are designed to tear others down. Not all lies are created equal.
