Is it right to lie about your reasons for needing a shift covered?

It’s never a good idea to lie about what’s going on in your life, even at work. It doesn’t engender trust, and trust is a hard thing to lose. It happens, though. Sometimes you just need to call out of work, and you need an excuse. Maybe you had something come up that day, a plan that you didn’t want to say no to, or something outside of your control came to pass. You need your shift covered, and you know who you need to ask for it. But you’re worried that they might say no, so you exaggerate your story. This isn’t a great idea, because it’s never right to deceive someone. You wouldn’t want someone to deceive you, so you shouldn’t deceive them. But sometimes it happens, and that’s exactly what happened in this story, where a coworker found out that their colleague was lying to them. When you work closely with someone, you probably hope that you’re on the same team. That you’re in it together. But maybe you learn something that you feel betrayed by, and there is no going back. That’s what happened to the worker in this story, who found out that their coworker had been keeping the truth from them for quite some time.
