Should I push through as a wedding photographer?

I’ve been working as a destination wedding photographer for 4 years now and I’ve been around the country for weddings throughout the years. The only complaint I have for this job is the fact that the salary I earn is really small compared to other fotografia groups. I get paid per wedding so that means that when I travel out of town for about 2-3 days, I only get paid for one day. I don't have to spend for anything though since the client is responsible for the accommodations and everything but the fact is that working for about 12-14 hours per wedding and getting a relatively small amount of income is tiring. I’ve asked multiple times about raising my salary but to no avail. Now, my boss wants me to become a team leader for another group he’s planning to establish and the pay is still so low. Should I push through with the job or not? I need some conselhos and insight on this.
