I used to Archer.
Biggest PITA for me tbh.
I binned all my girls bar one in the end.
When they first came on they couldn't get enough of work.
Within 6 months (less for some!) they were late, finishing early, rushing, crap job, sometimes rude to the customer. It just went on. For the couple of quid they made me I couldn't be bothered anymore.
Just have one lady now, she's mid fifties and absolutely good as gold.
Need her as I only get the windows on this contract with the internal cleaning.
That's just my experience though-you may fare much better...
