Under Documents you see the credentials this family requires — CPR for sure, a license only if they ask for it, sometimes a TB test or a training such as dementia and stroke basics. Upload a copy, or tap I don't have one yet: the card then reads Getting it, due by a date, with the days left and where to get one (the Red Cross for CPR, free courses for training) and I have it now — upload when you do.
A license or CPR card within 30 days of expiring is amber, expired is red. If the family turned the block on and a declaration is overdue, open shifts are greyed with Your CPR card is overdue — upload it to pick up shifts. Hired by the family directly (not through an agency): CPR is due within 30 days of starting and never holds your first shift; after the due date with no card the family has checked, or with an expired one, you can't take new shifts until the family records it. Clock-out and pay are never blocked by paperwork.
Working through an agency that keeps your file on ExpressAgain: the copies on file with the agency count in each home it links you to, so you file a CPR card once. In that home the stricter of the family's rule and the agency's applies. Open your own Team file from Team on the organization panel to file a copy; the agency's office verifies it.
