impartial ear here.
working with family is tough. we have done it for years. the only thing that finally worked was to treat everyone the same. boy is that hard. you know your children..know what they are capable of. good and bad.
it makes it hard to not expect more out of them than you do a regular employee. and mrs bear...i have been right where you are. smack dab in the middle.
i finally had to let my kids fight their own battles. yes...one got fired a few times.
stick to your guns. don't take sides.
by having to treat all equal..just like state laws say....it does make it easier to get family to follow all company policies.

i hope your migraine gets better and you can get some peace.
pm me any time.
