Dear NAME,

Please remember that it's your turn to tidy the lounge this week. This
should only take ~5 minutes of your time. Please email me once this is
done.

If you are unable to tidy the lounge this week, please find someone to
replace you and let me know as soon as possible.

Best wishes,
Dravy
