Market Investigations Ltd engaged interviewers to conduct market research surveys. The company argued these interviewers were independent contractors, not employees, to avoid paying National Insurance contributions for them.
Whether the interviewers were employees or independent contractors for the purposes of National Insurance contributions, and what test should determine employment status.
