Depending on how long you are unallocated (on the bench) at TCS, missing work could have a few different outcomes based on corporate policy and duration. This is an explanation:

Attendance and Performance:

It’s possible that TCS has rules on work hours and attendance. If you don’t arrive at work without permission, it could be taken seriously and negatively impact your performance grade. It is expected that you will take some initiative, even if you are not given a project.

Project Allocation and Career Impact:

Managers looking to fill project responsibilities may find you less apparent if you are physically absent. This can prevent you from moving up the TCS career ladder and postpone your assignment to a new project. Long-term absences could also raise questions about your work ethic and level of dedication.

It is essential that you interact with your management in order to reduce these dangers. If your employment permits it, describe your circumstances and ask about the possibility of working remotely. During your free time, actively look for internal project opportunities or training courses to demonstrate your initiative. By being proactive, you can keep a good record with your manager and increase your chances of being assigned to a new project soon.
