Golden handcuffs is a term used when people are promised a lot of money or other valuable things to stay in their job for a long time, even if they might want to leave. It's like a shiny, pretty handcuff that keeps them tied to their job because they don't want to lose all the good stuff they were promised.
For example, imagine a man named Bob who works for a company that makes video games. His boss tells him that if he stays with the company for five years, he will get a really big bonus of $100,000. Bob really wants that money, so he decides to stay with the company even if he starts to hate his job or wants to try something else. The big bonus is like the golden handcuffs that keep Bob tied to his job.
But even though the bonus might be really tempting, it's important for people to make sure they still enjoy their job and aren't sacrificing their happiness just for the promise of money or other rewards.
