Trending @Cognizant; Should I confront my manager?

My client doesn't want to pay for extra resources so I'm getting released from project in 10 days.

These last few days I've worked like I have never before. All day, all night. I have one pending work left. After that I'll probably not be assigned anything else.

I'm left thinking if I should even go the extra mile when these guys didn't care about me. I'll get released in 10 days, I should be using my time to upskill instead of slogging for them.

My manager also asked to give kt to the other person who is staying back in the project. Maybe that person should be slogging instead of me. All this for a bare minimum payment at the end of the month and my manager also shouted at me today telling me that I don't do any work.

I'm confused I just wanna chill and hand over my work. Should I confront my manager and tell him that?
