If your not charging £15/hour self employed go and work in a supermarket you'll be better off.
a bad farmer.... unless you count the vehicle , house, bills etc the business pays. Why do we all insist on saying how bloody hard we work yet also saying how little we are worth!!!!Great many self employed trailer jockeys and general farm workers are on a tenner, all very well people quoting £15-18/hr but the worker would be earning more than the farmer.
