Working at the kitchen table can collide with lunch, phone calls and someone looking for a charger. A shared room has several uses. Expecting everyone to infer which use matters at each moment leaves plenty of room for irritation.
Choose the few details that affect your work most. Perhaps you need quiet during a call, a clear table for an hour or a place to store papers afterwards. Ask what the other people need from the room at those times.
Try a small agreement
Agree on a visible signal and a limited period. A note beside the laptop might indicate a call ending at two. Include what happens after that time so the space returns to shared use without another negotiation.
Review the arrangement after a few ordinary days. If meals or schoolwork keep interrupting it, change the time or location. A household agreement should accommodate the people who live there, including anyone whose needs are harder to schedule. Keep asking about the actual collisions rather than arguing over who cares more.
