Donna Morris, Executive Vice President and Chief People Officer at Walmart, has shared the ultimate red flag that could stall an employee’s career growth: being a “Debbie Downer.”

Morris, who oversees the employee experience of 2.1 million Walmart workers, told CNBC Make It that constant negativity is a major barrier to professional success.

“Nobody wants to hire a Debbie Downer,” Morris said. “They show up with problems but never solutions. I prefer people who bring the problem and an idea for fixing it.”

Why Negativity Can Kill Your Career

A “Debbie Downer” is the employee who:

Criticizes colleagues’ ideas without offering solutions

Resists new projects or changes in the workplace

Hinders team morale and trust from managers

Career experts warn that such behavior limits networking opportunities and stops promotions.

Juliette Han, a Harvard-trained neuroscientist, says negative co-workers often restrict growth: “They discourage you from meeting new people or taking on projects that don’t benefit them directly.”

While toxic optimism is also unhelpful, Morris advises that persistent negativity might signal that you’re in the wrong job or company.

How to Get Ahead in Your Career

Morris shared key “green flags” that make employees stand out:

Deliver Results Consistently – Meet or beat deadlines and overdeliver when possible.

Take Initiative – Volunteer for projects and bring solutions rather than problems.

Be a Mentor and Team Player – Helping others signals leadership potential.

Show Intellectual Curiosity – Research trends, test new tools like AI, and share insights with your boss.

“People who you see are actually helping others – that’s a total green flag,” Morris emphasized.
