GLA chief Paul Broadbent visited Hammond Produce near Retford recently as part of a fact-finding mission to understand the challenges that farmers and growers face.
He said: “It is vital that farmers are given a level playing field so those that play by the rules do not lose out to the ones who cut corners.
“Seeing operations like the one I visited today - where the workers came from one of our licensed suppliers, were paid a decent wage and treated well - makes me more determined to tackle any producers out there that operate illegally.”
