I was a smoker for 50 years. I never lost days from smoking illness. Had flu a couple times.. We worked as hard or harder then everybody else...
Same deal, though less time.
I even worked manufacturing at one point. Ran circles around everyone else in the dept.
I’ve seen plenty of non smokers blow entire days, if not weeks, on water cooler conversation and internet browsing.
You’re either a good worker or not.
Some folks just really hate smokers (you may have noticed).
I quit in March of 86.
A new Chevy Caprice company car smelled so good I could bring myself to smoke in it.
