Summer ductwork in Florida

Okay I’m an installer and I know what I’ve signed up for 3 years ago when I got in the field, so feel free to call me out if I’m wrong. My company went out of their way to express that there will no more entire duct system changeouts for the summer after June, here we are near the end of July and I’ve been given the task to change 23 runs of metal ductwork to flex with duct board boxes and cut in 5 new returns and add a mini split. We’ve been given 3 days to complete this job with 2 people, we get paid fairly well $650 flat for just showing up for duct work and $90 for ever run over 10 $150 for a mini split. My manager pressed me this morning when I called him out. He said do you wanna work or go home and I was silently furious. My co worker has a fucked knee and he’s a xxl kinda guy wouldn’t do a lot to help make progress today as the “lead”. I’m willing to go through with it and do my best but I’m mad that I was lied to with the ductwork for the summer and there’s no help offered so far as plans, material list, or extra bodies. This ain’t right. Am I wrong?
