Hiring her to do something that would probably be one or two days a month of work does not cost him money as he can easily do this himself.
Again, he does not want to spend any more of his precious time doing this and having Dijana doing it is his own clever way of funnelling money to her through the company as a paid employee.
Sounds like a tax dodge. I wonder if she actually does any work, or just has a tax-free allowance to use up?
"install a light for after dark tasks"
Is it just me, or did everyone else think that's a euphemism for "hookers"? Or maybe it's his little wanking shed?
Anything he says now just sounds seedy ...
