13 things you should never say at work that most people don't know

“You can say, ‘I understand this was wrong, and it won’t happen again.’” he wrote. “But consider leaving the apologies to your personal life. Apologies are purely emotional. Acknowledging the problem and saying how you will correct it is a lot more professionally valuable.”

McCammon said his advice on this has changed a bit since 2016, when the book was published.

“My thinking on this has evolved a little,” he told Business Insider. “Let’s say you interrupted someone in a meeting, derailing a big pitch to the boss. That’s something you should apologize for. I think men are waking up to the fact that we tend to do this in meetings — to women especially — and it’s not cool, and it requires an apology.”

“People like to ask this after making a point,” McCammon wrote. “If you have to ask this, then you either are not confident in what you just said or you don’t know what you just said and you are now asking the person listening to your nonsense to validate it.”

In short, it can make you sound wimpy. It’s better to be confident and avoid undermining or minimizing yourself and your work.

Instead, ask, “What are your thoughts?” career coach Sophia Mohr suggested.

“Yes, but what is it?” McCammon wrote. “If you take this idea to its natural conclusion you will end up smoking a cigarette while jumping off a cliff. We must all resolve to stop saying this. It means nothing. It is a mantra for idiots.”

McCammon is adamant about this. “You may think at work,” he wrote, “But you may not feel.”

The phrase a silence-filler that communicates doubt about your work and yourself. Instead, try “I believe” or “I’m certain.”

Shaunna Keller, head of digital and social at national advertising agency Brand Content, told BestLife, “It could be the most informed opinion out there, but it’s interpreted as what YOU personally want and almost nobody cares about your personal feelings — they care about what the people they are creating the work for care about, want, need, desire.”

“In fact, no berating ever,” McCammon wrote. “Also: No berets.”

Yelling at a colleague in front of others is a form of public shaming, which amplifies humiliation. Don't do it, ever.

"If you don’t explain that you overslept, there still exists the possibility that you’ve spent the last thirty minutes cradling an injured bird in your hands,” he wrote. Instead, try saying nothing. “Discretion is a virtue. The most underrated tactic in the workplace is silence."

“Understand that crying is part of an important physical response to stress that makes us feel better,” McCammon wrote. “As intense and sad as it appears, crying is the beginning of feeling better. And so let them cry. … You don’t want to suppress it.”

This “nullifies the statement’s impact and substance,” McCammon wrote.

“Unless of course you are literally in a swamp or being slammed, overloaded, or pulled in all directions,” he wrote.

If you put yourself in the listener’s shoes, you’ll find you’re probably making them feel less than important when you say you’re “too busy.”

“Launch it, push it into the stream, yell at it with a bullhorn until it scowls at you,” he wrote.

Or any client, for that matter.

“Never start off a sentence with ‘Well … ’” McCammon wrote. “Leave ‘well’ to the airline pilots (‘Well, folks, we just heard from the tower, and it’s a total s--- show’).” He added, “Nothing good has ever come after the word ‘well.’”
