My work timings go on from 11 in morning to 10 at night, I'm a digital hire. How do I convince my manager for release from the project?

If you are someone who works from 11am to 10pm, they need you , you are useful to them and they wont release you :)

Be less useful, limit your time, take time to deliver the output.

Dont argue. Just pretend to be a helpless/dumb person when your manager asks you to work more.

For every associate timeing should be 9 hours. If they ask more time every day than create a graviance and ask for release

If you learning from the project stay there just learn how to manage your time.. I think you seems to tuning away instead of facing the problem.. do not work more than 8 hours a day not because that is what you are paid for but rather this is what you should achieve by becoming a smart worker. Managing time and expectations.
