Sure, try 'I'm at capacity right now, but let's circle back in a couple weeks.' It shows initiative without committing. If they push, mention how the last 'quick' project ate your weekends. I've used that and it worked without backlash. Keeps you looking proactive. Or pivot to 'Happy to help prioritize if needed.'
Push back anytime the invite can't answer two questions: what decision is being made, and why you specifically are needed. If there's no agenda, decline. If you're buried under a real deadline or customer impact, that takes priority; say so plainly. "Optional" means you skip unless someone explains the need. If it's just status, move it to a doc or email. Default 60 minutes for a 10‑minute topic? Ask for 15. Recurring sessions with no outcomes after a couple rounds should be paused until someone can justify them.
Be direct and offer an alternative so you don't look obstructive: a short written update, questions in a shared doc, or a 15‑minute huddle later. Call out time‑zone nonsense and ask for a humane slot. If a leader insists you attend without a purpose, put it back on them: what decision will be made that needs your input, and what happens if you don't attend.
