An untidy workplace is an inefficient workplace with a higher risk of accident .Keep in mind also that if they're cleaning up then that's their time too. What do you want to pay them to do? Clean up (which you can do)? Or get on with the task they're skilled to do?.

Definitions of 'tidy' are obviously variable!
I have some sympathies for workmen when they are on an on-going job; to leave a place spotless at the end of the day just to make a mess again the following morning is a bit daft. Depends on the circumstances though obviously. There's a difference between working in someone's house and on an empty site, so different standards of tidiness are to be applied and expected.

Personally, as long as there's a token effort to tidy up during a job and a bigger effort at the end, then I'm happy. In truth, I'm pleasantly surprised by the standards of tidiness shown by most workmen. It's probably an area that many are aware of as being part of the service, as someone above indicated.
