Sacrifice your health for the client - Associate Apex Group Employee Review

My senior literally said "sacrifice your health for the client. You need to invest your health". **NEED HELP!!** and not sure if HR will support it's employees. Client expects a week's task to be delivered in a day. No weekend off, no weekend pay. Managers and VPs boast about working 16+ hours a day like it's some big achievement to be proud of. In real no benefits. Turns off AC to save electricity bill and let employees suffocate and gasp.
