10 Things You Should Never Tell Your Manager or Boss If You Want to Protect Your Career

With mass layoffs still hitting tech, retail, and corporate offices this summer — and mid-year performance reviews happening right now — what you say to your manager this week matters more than ever.

HR experts say these 10 phrases can quietly flag you as a flight risk, a complainer, or not a team player — even if you mean well. Here are the 10 things you should never tell your manager if you want to protect your career…

Success at work isn’t determined solely by performance—it’s also shaped by communication. The way you interact with your manager influences how you’re perceived as a professional, whether you’re viewed as trustworthy, and how you’re considered for future leadership opportunities.

While honesty is essential, discretion is equally valuable. Certain conversations are best handled through formal channels or saved for the appropriate time and place. Understanding the difference can help you avoid unnecessary misunderstandings and maintain a strong professional reputation.

1. Personal Information or Gossip About Coworkers

Your manager does not need to hear rumors or personal details about your coworkers unless the information directly affects workplace safety, harassment, discrimination, or job performance.

Sharing gossip can make you appear untrustworthy and may damage team morale. Instead, focus conversations on work-related issues and allow coworkers to maintain their privacy.

2. Constant Complaints Without Solutions

If you disagree with a company policy or management decision, approach the conversation professionally and be prepared to offer possible solutions.

Repeatedly complaining without suggesting improvements can make you appear negative rather than proactive. When appropriate, raise concerns during performance reviews, team meetings, or through Human Resources if the issue involves workplace policies or misconduct.

3. That You’re Actively Interviewing Elsewhere

Unless you’ve decided to resign or have a strategic reason for discussing your career plans, avoid telling your manager that you’re actively interviewing for other jobs.

While every workplace is different, revealing an active job search too early may affect future projects, promotions, or how your commitment to the team is perceived.

4. Negative Comments About the Company, Clients, or Customers

Constructive feedback is valuable, but constantly speaking negatively about your employer, leadership, clients, or customers can hurt your professional reputation.

If you encounter problems, discuss them respectfully and focus on improving the situation rather than venting frustration.

5. Confidential or Proprietary Information

Never share confidential company information, trade secrets, financial data, customer information, or private business strategies unless you are authorized to do so.

Protecting sensitive information demonstrates professionalism and helps maintain trust with both your employer and clients. Violating confidentiality policies could result in disciplinary action or legal consequences.

Your manager and colleagues expect you to maintain confidentiality and protect the company’s proprietary information. Sharing such information can lead to serious consequences, including termination of employment.

6. Indications that you are not committed to your current job or the company:

If you are not committed to your current role or the company, it is best to address this with your manager directly and discuss any issues you may have. Showing a lack of interest or commitment can create a negative perception of you within the company and may lead to poor performance or termination of employment. It can also reduce your chances of a promotion.

7. Suggestions that you are not willing to work hard or put in extra effort:

Your manager and colleagues expect you to be a hard worker and willing to put in extra effort when necessary. Showing a lack of willingness to work hard or put in extra effort can create a negative perception of you within the company and may lead to poor performance or termination of employment.

8. Indications that you are not a team player or that you do not work well with others:

Your manager and colleagues expect you to be a team player and work well with others. Showing a lack of willingness to work as part of a team or difficulty in working with others can create a negative perception of you within the company and may lead to poor performance or termination of employment, and once again, can deeply hinder your chances at a promotion.

9. Any indication that you are not willing to adapt to new technologies or new ways of doing things:

Your manager and colleagues expect you to be open to new technologies and new ways of doing things. Showing a lack of willingness to adapt can create a negative perception of you within the company and may lead to poor performance or termination of employment. Take the time to learn the new procedures.

10. Refusing to take ownership of your mistake or taking credit for others’ work:

Your manager and colleagues expect you to take responsibility for your actions and own up to your mistakes. Taking credit for others’ work can create a negative perception of you within the company and may lead to poor performance or termination of employment.
