Walk on eggshells
means to act very carefully around someone or in a situation, usually because you don’t want to upset anyone or make things worse. It’s like stepping lightly to avoid breaking something fragile—like eggshells.

Examples:
1- After the company’s major merger, employees felt they had to walk on eggshells around their new boss, who had a reputation for being strict.
2- During the holidays, we had to walk on eggshells around Uncle Joe because he was still upset about an old argument.
