I had a bloke that missed window`s on houses every week i have now finally found out after 3 months,it`s funny when you sack someone that`s when you find out what the customers really thought of them,there reluctant to give you an honest opinion when there still working for you.A lot of customers don`t like you changing your staff all the time,they like to know the job is getting done properly without having to go round checking.
