So I was at work doing my stuff while the boss was late to the office for about 4 hours. No big deal, because it's the end of the season and there isn't much work to do. I had already gone to get lunch and was working on my side project. Then I took a small smoke break. To my horror, when I returned and opened the office door, my boss was staring at my open laptop screen. He then asked me what company X is? And asked me if I started my own company. I answered that I was just putting my skills into practice. He then gave me a lecture about not doing this at work. That statement was amusing because I know for a fact, that he himself occasionally works in a different company while working here. So I'm sitting here baffled about what to do. I really didn't want to disclose this information to him, because my personal business still hasn't grown to anything yet and I rely on my job as my main source of income. I'm not opposed to the idea of still working with my current company if the terms are right. To me, the most questionable thing was when I asked him if he looked through my computer he answered that he saw big letters and wanted to take a closer look. Like what even is that thought process?
