"The higher your level of education the more likely you are to ignore it because you can find more interesting things to do with your time."
I sincerely hope you didn't say that to your cleaner, biglouis.
If you did, I'm shocked.
It is up to you, of course, if you don't want her to touch certain areas and I can understand an office and keyboard might be one.
However, everyone has their value and place in society and without her valuable experience and hard work, you might be living in a filthy, unhygienic tip because you consider cleaning is beneath you.
Disliking cleaning is one thing, being contemptuous of those who earn their living cleaning other people's dirt is wrong.
They are worthy of praise and admiration imo.
