Time For Another Job
When people have time off, bosses need to respect that. There’s a reason people get approved vacation days. This person has one of those horrible bosses that clearly doesn’t understand the concept of time off. They were responsible and made it clear that they were on vacation, which this boss completely ignored.
They need to find another employee who isn’t off from work. We’d understand if they just decided not to come into work, but since they’re on vacation, there’s no real reason to fire them. Let’s hope this person finds another job where their boss doesn’t treat them like this (via Food Is In The House).
