If our suppliers understand that our customers will be asking questions about working conditions, child labour and the ethical sourcing of materials, and that the answers will influence your purchasing decisions, then it keeps the ball rolling for ongoing improvements. That is why your role is so important, giving you enormous power for change.
Although I would disagree, to the majority of the general public hard landscaping isn't that sexy. You may remember the furore caused in 2008 by the revelation that Primark's suppliers used child labour, which was followed by Primark's ultra-swift response in sacking some of those suppliers before its high-street reputation was irrevocably tarnished.
Sadly, landscaping materials are unlikely to capture the public imagination in the same way. We will, I think, be waiting a long time for a media spotlight to shine on poor health and safety in distant quarries. Where does this put landscapers and garden designers? Right on the front line of raising awareness.
Communication is the key. Clients not unreasonably want to know why they shouldn't buy stone on eBay for a fraction of the cost at which you find it. They need to understand the difference in quality, and the false economy of laying cheap paving created with cheap, unskilled labour. It's something that can only enhance a contractor's image, if it's clear that you ask your suppliers the hard questions: what are they doing to improve conditions for workers? Do they understand the supply chains that produce the stone? Have they looked beyond Tier 1 to Tiers 2 and 3 (stockyards and quarries)?
