Labor, whether "in the Family" or not, is still labor...
"Employees" generally cost more because THEN, you're faced with all kinds of tax returns, reports, etc. that does take a lot of time and expense over and above the simple labor cost.
"Partners" make it a little easier... BUT, they still want their money... Yes?
They normally get their money by Drawing from the company, keeping good records, of course. Then one Partnership Tax return is prepared and the split-up reports (K-1's) given to the individuals... They have to pay their own Estimated Taxes, etc. but the Reports, etc. (PITA) are bypassed.
... at least that's the way I last remember it to be...
Labor is Labor... money is money... And we're ALL underpaid... right?
Those are good ideas about the lighting... I was thinking about having a planer, jointer, and table saw all turned on & running at the same time... Without individual circuits, would be a big problem.
