Act busy to avoid getting more work assigned. If you’re already busy, act busier. Rinse and repeat. This also works if you want to avoid chatting with coworkers. If they want to ask you questions about work stuff, tell them to throw a meeting on your calendar. 90% of people from my experience will never willingly schedule a meeting but be prepared for the 10% that will. None of this is a guarantee of smooth sailing but it helps make the daily less rocky.

Good luck!
