I think it depends on the attitude of the employer.
Even when employing an 'unskilled pair of hands' one should explain gently but clearly at first what is required, and give help and support if needed. This builds the confidence of the worker, and will result in a good standard of work. This is far from 'inspection' or 'monitoring'. It's actually a kindness, and helps with the development of new skills.

I was always grateful when the employer made it clear exactly what they wanted in the way of cleaning, and I knew precisely what to do in the time allowed. Once everything began, I was left to do my little job, as I was trusted to do it properly.

Contrast this with those Ofsted demons! After over twenty years' experience, I was treated to a pompous ass trying to 'correct my methods' by implementing the latest fad in Education. One even interrupted my lesson and proceeded to demonstrate to my bemused class the 'right' way to proceed. I was fuming. It's not that I'm so arrogant as to think I'm always right. But this chap was honestly a real twit. He couldn't have taught my Siamese cat how to eat a bit of chicken.
