Hi Jan,
Ok, I have tried several different ways to answer this for you and I hope this way helps and makes sense.
First you should explain to your friend, that you are under contract with your clients that you will provide a cleaner for x amount of hours and that she will have to be their for that amount of time otherwise the client can and will refuse payment (don’t know what your contracts are). Also explain that in order to protect her employment, you need to renew these contracts and the only way you can renew them is by providing the service you have stipulated. Ask her nicely to take a bit more time when cleaning to use up those hours.
I would also explain to her that you feel when she is on top form she is a good asset to you, however, other times she lets herself down. You would also like to continue to employ her, however, you have a business to run and also clients to provide for and you cannot afford to be let down by any employee let alone a friend.
Don’t forget you are there for her, which she needs to realise, look after your staff and in return they will look after you. Ask her if she needs a holiday to sort her problems out, this may well work. But most important, you do need to stress how important contact is and any problems which may affect your business, need to be reported straight away.
As for your two clients, we all have the awkward ones, no matter how good you or your staff are, they will find something to complain about. First I would offer these two clients a different cleaner (if one is available), you could explain to them, that by putting a new cleaner in, would really benefit them. However, on the other hand, are these two contracts worth keeping on board? Some contracts are more trouble than they are worth and personally, if I had constant problems from the beginning I would have no alternative but to cancel them. Providing it was a problem with the client and not my staff. Also from previous experience, I have had clients that have constantly complained and upon checking the contracts and the cleaners, there was no merit for a complaint. The problem was the client didn’t for what ever reason like that particular cleaner. A change can be good.
Well I have babbled on a good bit, but hopefully I have provided you with one or two answers.
Good Luck and I hope it gets sorted out for you.
