Your business model is wrong.
:point_up: This
It's not that your business model is just wrong, you're a garbage employer. If 10 hour days are "the norm" then you can't plan for shit.
Hire more people to work realistic hours.
Are you a JW? If so, you're using your connection to the religion to hire people on the cheap and take advantage of the fact that some people think it's noble or whatever to "support their brothers".
The statistical chance that an elder and 2 MS's happened to be the best people to hire are low to zero.
