Twenty-first century workplaces may look and feel more casual than ever — with relaxed dress codes, open floor plans and flexible organizational structures — yet there remain unspoken rules about how employees should speak to their managers. “Social media and remote work have loosened boundaries. Because formality has eroded, people are more at ease,” said Kelly Bergeron, an executive coach at Novateur Partners in Atlanta, Georgia.
Bergeron, a former Marine Corps officer and chief human relations officer who is certified through the Worldwide Association of Business Coaches (WABC), mentors professionals to become stronger leaders. She’s seen many avoidable problems arise when employees don’t think before they speak. “People get lulled into informality with the boss and others. The boundaries still exist; they’re just less rigid or defined,” she said.
Below is a practical guide to what not to say to your boss and how to phrase better alternatives.
No. 1
Excessive casualness can come across as disrespectful. Familiarity doesn’t always translate upward. “I’ve seen employees dig a hole by assuming an informal tone will be accepted by board members,” Bergeron said. In higher-level meetings, flippancy is still inappropriate. Use professional language to show you can deliver.
No. 2
Honesty is important, but if you don’t know an answer, say so and offer a plan to find it. Rather than a curt “I don’t know,” try: “I’m not sure of the answer, but I know how to find out. Let me gather the data and report back.” That response shows resourcefulness and initiative.
No. 3
Friendly relationships are natural, but keep personal details limited. “Bosses don’t want to hear about what you did on the weekend,” Bergeron said. They want to know how you’re contributing to the organization’s goals. Keep conversations focused on work and save intimate or sensational details for outside the office.
No. 4
Avoid blaming others or using excuses like “I wasn’t shown how to do that.” Such comments frustrate managers. Instead, accept responsibility for your role and ask what training or resources will help you complete the task successfully.
No. 5
Avoid discussing divisive topics such as politics and religion. Even if you think your views align with colleagues, these subjects can create tension and don’t belong in professional settings.
No. 6
Don’t barge in demanding a raise. Managers prefer a calm, performance-focused conversation. Try: “I’d like to discuss my performance and get your feedback. When might I be considered for a compensation review based on my results?” This frames the topic constructively and eases the conversation.
No. 7
Profanity undermines credibility. Even in casual workplaces, swearing can make you seem less professional and could attract HR scrutiny in more conservative environments. Maintain clear, polished language.
No. 8
Badmouthing colleagues to your boss is risky and rarely respected. Bergeron notes it often backfires: managers may think the complainer can’t be trusted. If asked about someone else, answer honestly but without excessive criticism.
No. 9
Saying “Why should I do that?” signals you’re not a team player. A better approach is: “I’m eager to contribute and develop skills A and B. Can I get opportunities on this project to build those experiences?” That shows commitment and aligns your goals with the team’s needs.
No. 10
Avoid “I can’t.” If a task is unfamiliar, say: “I’m eager to learn this, but I haven’t done it before. Can you point me to the right person or resource so I can perform well?” This demonstrates adaptability and a willingness to grow.
No. 11
Managers don’t want to think you’re wasting company time. If you find yourself under-challenged, ask for additional projects that build competencies after you finish assigned work. That shows initiative and commitment to development.
No. 12
Your off-duty choices are your business, but when on the clock your boss expects you to perform. Even if you had a rough night, arrive ready to contribute and give your best effort at work.
No. 13
Assumptions create misunderstandings. If you’re unclear about processes or expectations, ask questions at the start of a project so everyone aligns and avoids avoidable mistakes.
No. 14
In today’s boundaryless work environment, “I didn’t have time” can alarm managers. If workload is unmanageable, say: “I’m having trouble completing all my tasks at the quality I expect. Can you help me prioritize so I can focus on the most important projects?” This opens a helpful conversation about priorities.
No. 15
Never threaten to quit. Bergeron advises asking for development and feedback instead. Threats signal instability and may prompt managers to plan your exit rather than invest in your growth.
No. 16
Dismissive replies like “That won’t work” show a lack of creativity. Try asking, “That’s interesting—how do you see it working?” Engaging in constructive dialogue demonstrates openness and can lead to unexpected solutions.
No. 17
Keep your boss informed if a deadline may slip. Bergeron recommends regular status updates: even if you’re behind, early communication gives your manager time to respond. Waiting until the due date risks missed expectations.
No. 18
Your boss pays for your time, so be responsive when asked for attention. At the same time, practice “managing up” by politely setting boundaries when needed: for example, “I’m happy to meet, but I’m closing in on the deadline for the project you assigned and want to ensure it stays on track.” This keeps your manager informed while protecting critical work time.
No. 19
Saying “I’m only here for the money” flags you as disengaged and possibly a flight risk. Jill Hand, managing consultant at hrQ, notes managers may question your commitment and productivity. Instead, emphasize growth opportunities: “I’d love to take this task on to learn and grow.”
No. 20
Avoid appearing inflexible. Most progress comes from creative thinking. If a colleague or manager proposes a new approach, ask clarifying questions about how it would work and offer ways to improve it.
No. 21
Everyone has unpleasant tasks, but constant complaining hurts your reputation. Tackle to-dos with a positive attitude; a cheerful approach makes you a more valuable team member and gets noticed by leadership.
No. 22
Statements that imply superiority create a negative atmosphere. Hand warns such comments damage team cohesion and may signal you’re shirking responsibility. Avoid lines that suggest you’re above routine work.
No. 23
Threatening to take over someone else’s role or implying someone’s job is unnecessary sounds immature and short-sighted. We often don’t see all the behind-the-scenes work others do. If you want to grow into higher responsibilities, ask to help on competency-building projects that add value.
No. 24
Complaining about customers is risky. Hand explains that speaking negatively about clients places a red flag on you; managers may conclude you can’t handle difficult relationships. Employees who can manage challenging customers often stand out and advance.
No. 25
An exasperated tone toward your manager signals disrespect. Hand says such an attitude limits your tenure on the team and suggests you may not be mature enough for the role. Keep conversations calm and professional.
No. 26
Comments about a superior’s appearance are risky, even if intended as a compliment. Personal remarks can be misinterpreted; stick to neutral, work-focused topics.
No. 27
Getting too comfortable at work is dangerous. Hand advises against displaying apathy or sloppiness; even on low-energy days, maintain professionalism. While everyone has off moments, staying engaged while on the company’s time is essential.
No. 28
Be honest in interviews and at work. If you overstated skills to get hired, it will likely surface later. Hand notes that exaggerations often come back to haunt employees; you’re expected to deliver on the abilities you claimed during hiring. Focus on developing the skills you promised and ask for training where needed.
Following these guidelines helps maintain professional relationships, builds credibility, and positions you as a reliable, growth-minded employee. Thoughtful language and constructive approaches will keep you aligned with managerial expectations and help your career progress.
