Capitalism...... It is just being sensible, Asda, Tesco do the same.
.
there is a w/c near me who worked for another w/c before he went it alone and he targeted a load of the other w/cs work and got it.
he told me he was treated like a dog while he worked for the other w/c and was paid £6-50 ph and was doing all the ladder work.
he said the final straw was when he was left to do a full internal/external clean on a large house including fascia and gutters, said the job was a cash job ( £200 ) and said the other w/c arrived about 10 mins from him finishing and when he got paid the owner gave him an extra £50 for a great job done and he said he never gave him a penny out of it.
have seen the other w/c a few times since and he seems to have a different bloke with him every time.
