I worked construction (hot tar roofing in Louisiana) for about 5 years. Even though we honestly worked sun up to sun down, occasionally we were forced to work on Sundays...
It never worked out in our favor.
Equipment broke, crap happened, work had to be redone, or we got rained on. And then get up Monday morning before sun up and start all over again - unrested, out of energy and with no motivation.
Folks need a day of rest for every 6 and Sundays seem to be the best for rest and family...works for Believers and unbelievers alike. But don’t waste it watching football!!!
We always ended up being more productive working 6 days than we ever were working straight 7's.
Plan B might be brainstorming something for November, even if it's just a B&B somewhere for you and Mrs. Haydudette to look forward to...(look up "The Inn and Spa at Intercourse" near Lancaster).
Sometimes having a fun future event in the plans makes the immediate endurable.
