"5. The Subpostmaster is not obliged to attend the sub-office personally but he is required, whether he is there or not, to accept full responsibility for the proper running of his sub-office and the efficient provision of those Post Office services which are required to be provided there. Retention of the appointment as Subpostmaster is dependent on the sub-office being well managed and the work performed properly to the satisfaction of the Post Office Counters Ltd."
" "employment" means employment under a contract of service or of apprenticeship or a contract personally to execute any work or labour, and related expressions shall be construed accordingly."
"It seems to us that this a provision in which the word "personally" has been quite deliberately inserted. "Employment," for the purposes of this statute, does not arise merely where there is a stipulation that work or labour shall be done. It is a contract personally to execute any work or labour. That, it seems to us, quite plainly requires that the person entering into a contract shall himself be under an obligation personally to do work or labour. It may well be that some of what he undertakes to do he may delegate; but in our judgment it is essential for there be "employment," that the person making the contract shall himself undertake to do, at any rate, some of the work or labour."
"(a) whether looking at the contract as a whole it contained on the part of the person who was contracting to provide services any obligation that he or she would personally execute any work or labour; and (b) whether that obligation was a dominant purpose of the contract."
