Many many many years ago, I split my business into 3 rounds as I had so much work, to cut a long story short I had 1 chap doing a 3rd of the round but he was never happy and was getting very greedy and needy always asking for more money etc, I ended up letting him go and he bought that third of the business from me and is still doing it today.
My son was also working for me as I provided him with a van and equipment, but he was useless and struggled to get all the work completed, I ended up making him come with me and we put the 2 thirds together to make it a manageable round for the 2 of us.
He ended up leaving me a couple of years later to take on a different job.
Finally I had another shiner whom I subbed out some of my commercial jobs, I ended up with complaints as he was not doing them to my standard. so I ended up letting him go and doing the work myself.
Approximately 4 years or so ago I sold off half the business and now my wife sometimes comes with me if I have a lot on
(more for company really)
All the above experiences put me off employing anyone again as it was too stressful , now days i get my days work done by 1pm and have no stress.
