Depends mate, are you going to employ him legitimate, this then goes down the route of employers insurance, holidays and all the other that comes with it
Or
Casual employment were they can be called in as and when required
Or
Cash in hand, were they come get paid and go home, no questions
Me personally am all commercial so only the top one applies, BUT........ If I was to be doing domestic work daily and majority of payments was cash then I wouldn't consider the top one and would be more inclined to consider the lower or lowest

one.
Benefits are there more in you do decide to expand and as your age increases there is always the possibility to rest more and let the guy do more.
Me personally I would defo go for it, I already have staff but am always on the look out for what I would consider to be decent lads with work ethic installed in the head, good lads will make you money so I will find work for them..........any one who thinks they going to turn up for work with me and stand around picking there backside gets told how it is
You are here to work, if you don't like it go find yourself a bus stop that will take you home, and that's it for them......down the rd
I think finding staff is the hardest part of it, training them is easy and finding work is easy, just not enough hours in the days
