As Karl Marx said, you get the best out of workers whose labour is not just a commodity. That thought may have lingered in the minds of Rooflight Company’s Peter and Val King, as 25 years since they started producing the ‘Conservation rooflight’, they’re transferring the firm to employee ownership this month. They say it offers ‘higher productivity… 25% increase in operating profits… more resilience to economic turbulence…more engaged, fulfilled and less strained workforce.’ Someone might have taken a hammer to Marx’s grave in Highgate cemetery recently, but you can’t knock those findings.
