My mom is fine, thanks. She has less pain in her hips now. Her leg is swollen, but all looks well for now. Today she was allowed to get up and walk with crutches.
And no, it's perfectly legal. The house does not forbid it, as long as no one exaggerates. I guess, it's in their own best interest that the employees care for their own health.
And another good news. The first rehab application was valid all along and she can go there immediately after the hospital. That's great.
