I'm in this boat. I told my manager, talked about my pay & how it doesn't match my responsibilities. I talked about how I'm OK with a little crunch, but crunch 52 weeks a year is not crunch, it's just taking advantage. He said he's aware of the situation and that everyone's in the same boat, as if that justifies it somehow. He said wait to ask for higher pay. I feel like I'm being jerked around. I hear this from you & I hear the same from some of my other friends in my field, too, so I doubt the grass is greener anywhere else, and leaving won't have much effect.
I liked my job in the past. I think I would like it again if my workload was more reasonable. The best I can do is just constantly try to set expectations that, no, I won't be putting in any more additional extra effort.
