This advice was given to me by someone who has worked for 20+ years in IT.
"The reward for work done is always more work."
So always manage you time properly here. If you keep working hard then you will be exploited by your manager. He will always take credit for your work. You will do the work but it will be presented by a dumb senior to the client.
So your strategy should be:
Always complete your work on the weekend. Then every day you need to reveal work done slowly. Monday to Friday. This way you will chill during the entire week. People will think you do work but in reality you are coasting and chilling.
Use this time to upskill and interview for other companies. Then get out of IT and go to a Product company.
