If you have no one else to look after your child and the jobs your partner have interviews for will help your family then i would phone your work and say that you have childcare issues and need the day off.

Of course take the day off!

Take the day off for sure.

Yanbu but I wouldn't call in sick yourself. That's wrong.

YANBU to take annual leave if your employer consents

As long as you don't pretend to be sick.

No you wouldn't.

Just take it as annual leave, rather than a sick day

I would take the day off but I would be honest about the reasons why, I.e. I wouldn't take a sicky.

Can you either ask for annual leave, or ask for parental leave? Parental leave may be unpaid but it exists to deal with unforeseen emergencies, such as having no childcare.

YANBU to ask for annual or parental leave at short notice.

You would BU to ring in sick.

Oh no I wouldn't call in sick, my employers are far more understanding with childcare issues than sickness.

It depends... if you're my assistant who's repeatedly been off sick/injured/children ill over the last 6 months I'd get your bum into work as the team are getting annoyed. And I've discovered your nickname was "sicknote" in a previous job.

If that's not you.... then ring work and get the day off.

Well of course yanbu, what's the alternative, leaving your DC to take care of themselves?
