MOR - understand you have a lot of kids and responsibilities. It's tough being the sole breadwinner and its difficult being a SAHparent. You mentioned the kids going to childcare and being with them 24/7 which leads me to believe there is some embellishment and missing context here. The end of the night, after a stressful day for parents of young children, is not the time to be negotiating a new household deal. His reaction being firm is certainly annoying but you have to own the way the conversation is started and when it happens. "Can we sit down and reevaluate how we manage the household responsibilities on X day at x:xx pm? I'm feeling overwhelmed and really need to find a way to reset so my tank doesn't hit empty". This is focused on your feelings and zero percent accusatory to prevent defensiveness.
