A simple trick to determine if you're oversharing at work, according to the CEO of CVS, is to recognize the 'fine line' between being helpful and being too forthcoming.

Navigating the art of befriending your colleagues requires a balance: Share enough about yourself to foster camaraderie, but be cautious not to overshare and risk embarrassment or damage to your reputation.

To achieve the right balance, Karen Lynch, CEO of CVS Health, advises sharing only what helps solve a problem or connect with someone else. If it doesn't meet either of these criteria, it should be left at home.

"Lynch, the owner of CVS retail chain, Aetna insurance company, and other brands, stated in a recent LinkedIn video series that there are topics that can be discussed to bring about change. However, there is a thin line between these discussions."

Mastering communication and public speaking is the ultimate guide.

As Aetna's president from 2015 to 2021, Lynch followed her own advice and ran a company-wide town hall early in her tenure, urging managers to take mental health more seriously. In an unplanned moment, she shared something she'd never told another colleague before: when she was 12, her mother committed suicide.

Lynch's upbringing was dramatically shaped by the experience, which defined the adult she became. Despite feeling ashamed, anxious, and embarrassed about it, she spent much of her career being strictly about business.

During the town hall meeting, with 50,000 employees present, Lynch realized she could help her colleagues comprehend her strong stance on mental health. Following the session, an employee contacted her.

Lynch stated that she had recently lost her son to suicide and did not wish to disclose this information to others. However, she added, "You made it okay," and she felt better after discussing it with someone, hoping that her story could help other mothers in a similar situation.

How to avoid oversharing

Lynch stated that the boundary between office banter and oversharing becomes indistinct when personal or sensitive information is disclosed excessively, as exemplified by the statement, "I got into a fight with my husband last night."

Experts suggest that it's important to be tactful when discussing sensitive topics in the office, practice active listening, and set healthy boundaries. Additionally, setting limits on how much time you spend chatting with colleagues can help prevent oversharing and maintain a healthy work environment.

Brandon Smith, a therapist and career coach known as The Workplace Therapist, advised CNBC Make It last week that if you have a colleague who overshares and dumps their personal life on you, and you don't have time for that, you can say, "I'm so sorry, I only have five minutes to chat."

Claire Wasserman, founder of Ladies Get Paid, advises against oversharing on professional networking websites. Instead, she suggests asking oneself, "What is my goal?" before posting personal comments.

"When I witness individuals discussing death in their families, I often wonder, "What message are you trying to convey?" Wasserman stated in 2022. "Any content you share should benefit another person and be related to professional assistance.""
