I'm curious about this rider asset thing. When the company I managed used self employed personnel I had a meeting with the then Inland Revenue to clarify exactly what "self employed" meant. In short, the answer was as soon as we, the employer, made any demands such as working hours, uniforms etc and tried to enforce these with sanctions those workers would be have to be treated as employed. Maybe the rules have changed in the last few years but I would have thought a self employed rider whose track has closed could go where he likes and any attempt to control this by the BSPA would be restraint of trade.
Genuinely would like to know the answer to this.
