conflict of interest
I guess you never heard of "conflict of interest" that word does not exist.
Would I love my son to work with me? if there is the slightest chance of favoritism NO THANKS!
That is one of the reason of your problems my friends!
The amazing thing to me is that you do not even see the problem or even consider it a problem.
I once learn you tell people once why the should not do something if they continue to do it let them. or in a not so nice terms "if you eat ****, I tell you once it is not good for you, if you continue to eat it, who am I to tell you not to"
