Lack of Empathy
It’s so shocking seeing some people with the tiniest amount of empathy in their hearts. This employer is the perfect example of that. We often hear that going through the same trauma makes people empathize with others better but not in this case.
Despite the fact that this boss lost his grandma and an uncle, he didn’t think twice before lashing out at an employee who lost their father a day before. So, we don’t blame the OP for quitting such a job where people have no empathy for your troubles or losses.
