Option 1

Discreetly and privately inform your colleague about the impending layoffs, advising them to start preparing their resume and exploring other opportunities without revealing the source of your information.

Option 2

Report the overheard information to HR or a senior manager, expressing your concern about the specific colleague and questioning the fairness or necessity of their layoff, hoping to intervene on their behalf.

Option 3

Keep the information entirely to yourself, respecting company confidentiality and hoping that your colleague will find out through official channels when the time comes, believing it's not your place to interfere.
