The advert may not have any impact on life at the meatworks, but it was an interesting way to give voice to a community, and is in keeping with a growing trend of public pressure on companies to do the right thing - even if it may not, at first glance, seem to be the most profitable thing.
Earlier this month, such pressure from conservationists prompted Fonterra to agree to only use responsibly-produced palm oil products.
