My Boss Comes To Office Late & Expects Team Members To Stay Overtime. He Schedules Most Of The Meetings After The Working Hours. We Do No Productive Work In Those Extra Hours. Is There A Way

As I see it, there are two parts to your concern. The first is about stretching of the working hours regularly due to meetings. My suggestion would be to try and have an honest conversation with your manager about this. Politely offer to fix these meetings in advance, preferably within working hours, and manage your time accordingly. If meetings after working hours is the only solution, try and see if your organization or your team can have flexible working hours. The second part of your problem is that meetings are unproductive. Are these meetings unproductive for the group in large or only you? This is a conversation you must have with your manager, and see how you can add value to these meetings. If it's unproductive for the whole group, discuss a structure with your boss to make the meetings more meaningful. If none of these work, you can do a skip level meeting with manager's boss and explain your predicament to him/her.

The only way to create a culture is to be an example yourself. You leave early or whenever you want to and ensure you are on top of your work always. Once you have demonstrated this consistently, it will become an example for others to emulate and hence it will pave way for massive influence thereby creating a culture.
