Employees or their representative may advertise their dispute with the agricultural employer and picket the employer. Employees or their representative shall not picket so as to interfere with the work of a neutral employer or supplier who is not involved in the dispute. A dispute between an independent contractor and agricultural employees or their representative shall not be deemed to be a labor dispute involving the farm or ranch, or the owner, lessee, or operator of the farm or ranch.
