People tend to work harder for cool managers, and as everyone learns at a young age, swearing is extremely cool. It’s said that the way to a man’s heart is through his stomach. In the office, the most direct way to a subordinate’s heart is through a foul mouth.
Casual swearing (e.g., “This coffee is sh&tty,” or “I’m out of f*cking staples? F*ck!”) sends a clear message to direct reports. It says, “Just because I make twice as much as you do, and determine when you can take time off, it doesn’t mean I’m not a rad dude/dudette.”
The message doesn’t always come across. Some people find swearing unprofessional, offensive, lazy or evidence of a limited vocabulary. As a counterpoint, these same people also tend to refer to marijuana as “the pot,” so take their criticisms with a grain of salt.
HR tip: Start with low grade swears like “damn” and “ass” before moving on to more advanced foul language.
