First of all, Richy needs to have in place a correctly worded contract of employment, they normally cost between £600 and £1000 depending on who does it and what you want in it.
Part of this contract would cover wages and hours of work, any employee who wants to question their wage would be pointed to the relevant paragraph.
Good staff are like rocking horse poop, and if you find one then try and keep them, but being strong armed is not the right way to go, because once he gets away with it, how long before he comes back to the table with more amendments to his contract of employment.
I use to pay my staff a daily rate, but I found that this was a unfair method for me and my staff, for instance if they cannot work due to breakdown or weather, then they never got paid. this is ok in the summer but come winter, they end up losing.
You have to think of them as well as your profits, they need to earn a certain amount to live, if they don't work and get paid for 1 day a week, it doesn't mean that their living costs drops by the same amount.
So now I pay all my staff a salary wage, this is set at the minimum wage of £6.08 times by 44 hours a week (this is was what my HR company say I needed to do) = £267.52 or £1160 a month.
If they cannot work because of bad weather then they still have a wage at the end of the month, that they can budget too, if there is a breakdown, well they can drop leaflets or doorknock, instead of cleaning.
Of course if you the boss are making a fortune from your staff, then they are more likely to either leave or their quality of workmanship will drop, so I also offer bonuses.
These are paid out on what they have done in the previous month, so even if they have lost a day or two in the month because of whatever reason, they still have the chance to catch up with the workload.
At the moment I set the wage bill with bonuses and employers taxes and costs at a third of my turnover.
I think this is a fair way for me and my staff, but if I still had someone who wanted more, then its the highway for him/her.
