I have worked for two different uncles. --one is my dad's brother, and the other is my mom's sister's husband. It can work out either good or bad. In the case of my dad's brother, it made us really really close for a while, but then when I started working for him on his house, and it was his money that was being burned up, it was like nothing I did was good enough. --And it really distanced us. To this day, we are little more than cordial.
On the other hand, I have worked for 3 years with the other uncle. One of the coolest people I've ever met. I got to know him a great deal better, the time spent was great, he thinks the WORLD of me now, and all in all, I think it was one of the most positive work experiences ever. It was like, he was a good and fair boss, but then there was always that family bond also. So I go the good stuff about being family, just to make it all even better. One bad thing though....if you are working FOR family, you may feel obligated to not quit them. In my case, I was part of a 3-man crew. It was me and my uncle at all times, and we always had at least one (and usually just one) other hand that traveled with us. We went through about 4 per summer on average (DAMN hard job on the road).... I was kinda like second in command, and I worked ahrder than anyone else (including my uncle at times, but not often...damn workhorse). He could NOT have handled it without me. He wouldn't have been able to find a worthy replacement, and certainly not on the short notice it would have required. Because of this, there was NO WAY I could have quit. If i had, it would have meant that i had left my uncle high and dry....and since this is a company that he took over after my grandfather died, the implications of me leaving that company out in the cold without any help would have run DEEP AND WIDE. I would never have lived it down with him, my aunt, my grandmother, or practically anyone else. Those thoughts made it kidna tough from time to time.
--But if you are just working WITH someone, I imagine it can go pretty well. --As long as it doesn't mess too much with the family dynamic (such as you being the manager over the new employee YOUR MOM).
