You can try and use holidays, special leave or unpaid leave. If you have a flexible job you might be okay but I would need the day off personally
I've been using my holiday entitlement, it's not really ideal but we don't have any other option as my husband is self employed. My mum can sometimes help but she's self employed too x
My work says to take it off sick using my sick days, just ask your manager and see what they say. It’s super common ☺️
