Partner's weekend lab runs and my on-call weeks landed on the same days twice this month
My partner's experiments don't care about calendars. Some need someone in the lab at 6 am on a Saturday, some at midnight. My on-call rota is fixed a month ahead, but I can get paged at any hour. Twice this month both happened at once, and the baby (8 months) spent the whole day with his grandmother. She lives with us and has been wonderful, but a full weekend day alone with a crawler is a lot to ask. How do other couples with two unpredictable jobs plan this? Shared calendar, a rule about who swaps, paid backup on those days?
