Trending @Capgemini; Working in shift

I have been into the current project since May 2024. I am working for a NAM client. During interview, I clearly asked them the work timing to which the managers and client managers informed that it’s 11 am to 7:30 pm- max 8 pm. To which I agreed. For first 2 months, we were informed that during KT sessions we might have to stretch till 9 pm IST. But, since the project started from scratch, we are still attending calls till 9:30 pm IST. I am very much particular about work- life balance and I have been always been perfect in my work. Should I wait patiently for another week to pass by or should I switch in other project?
