Allowing your personal problem interfere with your business is something that shouldn't be encouraged in anyway because it is capable of affecting your business in a very negative way in which you cannot even be able to explain yourself as a result of the nature of whatever personal problem you are having.. It's smart for a business owner to keep such things under wraps in order not to mess up his business.
Unfortunately, in many cases, many people may never consider this. Bosses are also humans and they could be experiencing many problems in their personal lives. This is why they may get frustrated and act in a bad way. A few employees may understand this. However, many simply won't.
