You must know how to stay discreet. In the workplace, a single mistake can have serious consequences: no promotion, stagnant salary, isolation, harassment, or even being quietly pushed out. In this video, Yves Gautier, a career coach specialized in professional communication, breaks down 7 common behaviors to avoid at all costs. Often made out of naivety or misplaced trust, these mistakes can seriously damage your career. Mistake #1 – Getting involved in gossip It may seem harmless to participate in office chatter, but it’s a slippery slope. Repeating rumors or aligning yourself with negative coworkers quickly labels you as untrustworthy. And anything you say can and will be used against you. Best practice: don’t listen, don’t repeat, and don’t engage. Mistake #2 – Criticizing your boss It’s tempting to vent about your manager, especially around colleagues. But criticizing leadership or the company’s direction puts your reputation at risk. It can make you seem disloyal or emotionally immature. Even when things seem absurd, it’s wiser to remain emotionally detached and focus on what you can control. Mistake #3 – Talking about your plans to leave Openly sharing your desire to quit or your side projects can backfire. Once your manager catches wind, they may stop investing in you, and HR will have no reason to negotiate a favorable exit. Even if you plan to leave, always act as if you’re committed long term. Mistake #4 – Discussing your salary Talking about your compensation can breed resentment. Those who negotiated less may feel cheated, and a chain reaction of complaints could create conflict with management. In the end, it makes you a problem, not a role model. Salary discussions are rarely productive. Mistake #5 – Oversharing your personal life In a professional setting, discretion is often smarter than openness. Sharing too much about your private life exposes you to judgment, jealousy, or gossip. Keep the conversation neutral and safe—stick to light, common topics in casual chats. Mistake #6 – Discussing politics (or religion) Politics is a minefield. Even light-hearted comments can create tension or end relationships. Humor or sarcasm doesn’t always translate well at work. It’s best to keep political and religious views out of the workplace entirely. Mistake #7 – Letting loose during boozy events The “hell combo,” according to Yves Gautier: alcohol, resentment, gossip, and careless revelations. One poorly managed company party can ruin your reputation. No one trusts the colleague who loses control after a few drinks. If you want to blend in, opt for sparkling water dressed up as champagne. Conclusion The main takeaway: don’t confuse colleagues with friends. The workplace is a competitive environment where anything you say may be remembered—and used against you. Discretion, professionalism, and emotional distance are your best tools. Learn how to hold space in conversations without oversharing.
