both my daughters work for me . 2 or 3 days a week each depending how busy I am
they both work very well, and are thorough.
now for me it isnt about me making money from them as such , { although I do now they are up to speed }
when they started , I made it clear to them , that i didnt want them to work at my pace .... they were to concentrate on the method and being thorough.
If ever I felt they were working too quiclkly. I would keep an eye and pull them back.
my customers like them, and have commented how thorough they are.
it may be because over the years they have seen how hard I work to get customers and keep them, or it may just be that women are just more thorough when it comes to cleaning.
