I employee, and do not have any of the above mentioned issues.
Yes, you get annoyed sometimes over things that they do, but these are soon rectified.
I find employing is most benifical for me in the winter. Those cold miserble mornings when you cant be bothered to go do that annoying mission of a house or street, but you have to cos your employee turns up for work. Once your out there tho its fine.
At the end of the day, I have more money as a result of employing so I shall continue to do so.
Peace
