Have you decided you would prefer your workers to be self-employed?  In fact, this decision isn’t down to you, but is determined by the facts of the relationship.  Get this right, becuase if you don’t, you (as an employer) could be clobbered with a tax bill for your workers further down the line.  To help you decide what the correct status is, check HM Revenue & Custom’s website, via this link:- http://www.hmrc.gov.uk/calcs/esi.htm
