Well, we can certainly agree to disagree here. 
I cannot help feel that it was a deliberate attempt on Alma's part to flaunt her disregard for Ennis's "authority" in front of her children (again, given the context of that society). It makes sense in the flow of events, because I think the intention of the film-makers was to show this as a way of her "getting back" at Ennis for the betrayal. As in all cases, a wrong does not make a right.
I see this scene very differently myself. First, I don't think it was a deliberate attempt at all by Alma to do anything other than go to work, preferably without being berated for it by the husband who makes it necessary for her to get a job in the first place and then harasses her for it. Second, I never thought Ang Lee was trying to show this as an attempt to "get back at" Ennis for anything. I just saw it as a way to show that Alma was losing her patience with both Ennis' behavior and her role in this marriage, and was finally starting to show some of her frustrations. That’s all. I can’t think of any reason why Alma would make a deliberate effort to flaunt her disregard for Ennis’ authority in front of the children. I’m not even sure I think she
had a disregard for his authority. I guess I also sort of think that ascribing a lot of ulterior motives to their behaviors is giving both of them credit for being much more analytical and insightful than I think either of them were. Alma wasn't planning anything here and neither was Ennis. She was trying to go to work. He was feeling frustrated or out of sorts (for whatever reason) and lashed out at her. That’s all I saw.
Yes, I was about to say this, but saw that you had already cited it. The fact that we see Ennis asking them that question showed that he at least tried to mitigate things (although his kicking the bucket after that didn't exactly help the situation.
) Perhaps Alma would have done the same, but we never see her do this. Hence, I do admit that this made me feel "better" about Ennis.
I think that for both of us, our initial impressions of this scene have shaped the way we see all of the different elements in it. Because again, it looked a little different to me. I saw Ennis turn away from a heated exchange with his wife (during which time neither of them were taking note of the children’s presence) and register that his girls were sitting on the swings looking at him. Now shifting back into the moment with his kids, he gruffly asks them if they need a push. Once they say no, he turns and kicks at the bucket in frustration and then walks away. He is obviously still in his frustration zone. If he were really trying to mitigate anything, he would have taken a deep breath, given them a smile, and paid some attention to them. It wasn’t Alma’s responsibility to do so in this case because she had to go. We have no way of knowing what her response might have been if she’d been the parent that stayed after the argument. Please understand that I’m not trying to criticize Ennis here. I just think that we’re looking at two people, who weren’t very sophisticated, doing the best they could with what they were given in life. Unfortunately for Alma, she was as much a victim of Ennis’ oppression as he was. Society wasn’t kind to either of them. But as far as I could see from the small glimpses Ang Lee gave us into her character, including this one, she rose to meet her circumstances with as much dignity as anyone could expect of her.
But serving dinner to the girls wasn't more important than her going to her necessary job! When Ennis could do it just as well. Even in the context of the times.

But was the job really more important? I question this. In fact, this is exactly the same fault we blame Ennis -- making his job an excuse to push back Alma, the girls, AND Jack. For example, was Ennis crazy to have dropped his job to attend Alma Jr.'s wedding? Granted, a wedding is more "important" than a dinner, but both symbolize the same level of prioritization and Ennis's shift after Jack's death.
Hence, if we don't spare Ennis for this same fault, I don't see why we have to spare Alma.
Well here we’re just arguing different points, not actually disagreeing. Because serving the girls dinner has nothing to do with Alma’s priorities or her job in the context of this scene. She isn’t choosing work over feeding her family. In fact, she’d already cooked their dinner. All Ennis had to do was put it on a plate and set it on the table for them. I don’t mean to sound argumentative but to me we’re adding an element to the mix that just isn’t there. If we’re saying that Alma should choose to take care of her children over going to work, even if she needs this job to provide for her family, then we should be looking at a time when she made a choice between the two. That’s not the case here. She fed her family
and she went to work, which means she covered both responsibilities. All Ennis had to do was be present with his kids for the evening. I’m sure my bias is showing here.

Even now, in 2008, it makes me nuts that so many people still say that when women are taking care of their kids, they’re being a mother but when men take care of their kids, they’re ’babysitting.’ Um…no. When you take care of someone else’s kids, you’re babysitting. When you take care of your own kids, you’re parenting. Imo, it wasn’t unreasonable to expect this of Ennis, even in that era.
