How forgiving is Appen about absences?

I just got on with Appen a few weeks ago and have been meeting the 20 hour per week requirement so far, but everyone in my house has the flu now. I tried to do some work today but I'm completely useless. Are they pretty forgiving about missed time as long as you record the absence properly on their site, or will they probably punt me for missing a few days? Thanks in advance.
