When i had lads working for me, i used to pay them 20-25% of the daily turnover, in other words, if they`re not working, they don`t get paid, the harder and quicker they work the more they earn.
20-25% of the daily turnover was working as a pair ( them and me )
OR, if they`re on their todd, i used to go 60-40, they earn 60, i eaqrn 40% of the daily turnover.
