hi, i work in a manufacturing company. from past quite some time we have been observing that the operators working at machines which gives us raw material for another product are not giving us correct quality of the material and because of this many of our consignements have been rejected. we have already tried speaking to the HODs and the shift incharge etc but no use. now we have been asked to communicate directly to the operators so that they understand that the company products were rejected because our raw material was not finished properly and this way we lost a good amount of money. could you please advise about what kind of communication tool i can use to communicate with the operator level employees. i need to make them understand the financial impact of their act on the overall company. since this is a manufacturing plant so i can not plan for any electronic media display.
