Unfortunately O.C. as in most walks of life quality gives way to quantity. My granddaughter is a carer and works for an agency and all these agencies are as bad as one another. It's the pen pushers and bean counters in these places that set the "schedules".
You can't tell them that no two days are alike, no two visits are alike, they give these carers almost impossible schedules to keep to, so if they turn up at a call and the lady has fallen and requires a bit more attention this is not taken into consideration back at base, maximum effort, minimum time.
A couple of times on my last job I delivered to o.a.p.'s and found them in distress. One such case, in Stocksbridge, the lady had fallen in her kitchen cracking the back of her head as she went down, when I arrived, as luck would have it she was lucid, so I got her up sat her on a kitchen chair and put a tea towel on the back of her head, I then contacted the carer service on the phone explained the situation and they said they would dispatch her carers straight away as normally they would not be there for at least another hour, so I decided to stay with her till help arrived, meanwhile I contacted her daughter {who lived about 80 miles away} and explained the situation and she said she would come straight away. 45 minutes later the carers finally turned up and decided to ring for an ambulance, I said if you had told me that's what you were going to do I could have done that and they would be here tending to her quicker than you getting here.
They told me off for picking her up off the floor saying they would have left her there till an ambulance had come and assessed her, so the poor old dear would have been flat on her back on a cold floor for over three hours.
All ended well in the end, The daughter sent our office an E mail saying after a few days in hospital her mother will now be living with her.
