Sub Contract Law

[Angels]

Hi.Have recently won work from sub contractor working for Mansells.We have sub contracted our part of the work and this seeems to be causing a problem to Mansell-we are asked to leave site.No idea what Mansell Contract has to say on this-sub letting from Sub Contractor.Has anyone any experience working with Mansells that know their Conditions on this aspect.Thanks.

Wrong kind of contracting, I think. Perhaps someone else can recall what the site is for contractors who actually produce things?
