It's one of those "swings and roundabouts" situations, isn't it?
There's me and two lads, but we don't get through the work in a third of the time that one man would do it in. Our working time per job is probably a third, but our travelling time between jobs is still the same as one man would do it in, but multiplied by three of course.
I look on having staff as my insurance policy:- if I was working as a one-man band, I wouldn't be earning if I was off ill or away on holiday. It's easier, and cheaper, to have the lads work on a bit longer if we're catching up after bad weather, or covering for someone who's off.
Sorry for my ramblings recs,
Think it through - you'll make a profit out of anyone who's working for you, or you wouldn't be employing them, so it's worthwhile having an extra pair of hands for the work available.
For instance:-
Your working rate is say £20 per hour. The rate you pay employees is say £7. You now work less hours until you bring in more business, but for every hour you now work with an employee, you make £33 instead of £20. Is there a problem here?
What's the point in selling off jobs that you've worked hard to get - you'll be lucky to get two months' turnover, and less than that on residential
