   I won't be able to take that shift myself, so it's worth checking who else on the rota is free.

Examples

What to avoid

• Over-explaining or inventing a reason makes it harder, since a short, clear no is easier to respect.
• Vague answers like “maybe” or “I'll try” don't help if your answer is really no.
• Apologizing again and again can make a simple no sound negotiable.
• A late reply leaves your manager or coworker stuck planning around you, so answer promptly.
• Criticism of how shifts are handed out belongs in a separate conversation, not in the same message as your no.
