So you work all weekends, and holidays? You don't take sick leave or family leave? All of those things are legally permitted to you.
So, you own your own business, making you the Board Chair. I would suggest finding a CEO. If you're already the CEO, you're in trouble as you're making a lot of work for yourself. If that's the case I would suggest finding someone to fill the role of President. Beyond that there's the:
CAO - chief administrative officer - usually a substitute for the COO; oversees daily operations.
CFO - chief financial officer - oversees all financial matters.
CIO - chief information officer - oversees all forms of information and ensures that data and information are protected.
CTO - chief technology officer - oversees information technology systems such as computers.
CMO - chief marketing officer - oversees marketing activities, i.e. advertising, public relations and social media marketing.
CHRO - chief human resources officer - oversees the hiring process, training and employee performance.
I am assuming that since you said it's a family business, you don't have enough staff to man those positions. I suggest then, having your business closed on weekends. I mean, you're free to do with your enterprise as you please, that's the beauty of it. Point being, you do have these freedoms listed above, you simply opt out.
Kinda like opting out of the Affordable Care Act. Or Public Education.
