Indeed, by their own account, workers' rights had nothing to do with the decision to revoke Uber's licence.
The socio-economic classification of Census 2001 indicated that the most common occupations were "lower managerial and professional occupations" (21.9 percent) and "small employers and own account workers" (15.2 percent).
Category I consisted of participants classified by the CSO as higher and lower professionals, and employers/managers and own account workers with third level education (n = 161).
Category II consisted of participants who were employers, manager or own account workers and did not have third level education (n = 64).
The self-coded version of the NS-SEC used in this study has five classes of occupation: managerial and professional; intermediate; small employers and own account workers; lower supervisory and technical; semi-routine and routine.
The five levels of classification were (a) managerial and professional occupations, (b) intermediate occupations, (c) small employers and own account workers, (d) lower supervisory and technical occupations, and (e) routine occupations and unemployed.
Demographic characteristics we took into account were age, sex, and social grade (AB = managerial and professional occupations, C1 = intermediate occupations, C2 = small employers and own account workers, D = lower supervisory and technical occupations, and E = semi-routine and routine occupations, never workers, and long-term unemployed).
We combined these factors by using an algorithm to derive the NS-SEC category for the sole or highest scoring parent/carer, in five groups: managerial and professional, intermediate, small employers and own account workers, lower supervisory and technical, and semi-routine and routine occupations.
38 The NS-SEC grouped the participants into eight occupational classes: (1) higher managerial, administrative and professional; (2) Lower managerial, administrative and professional; (3) Intermediate; (4) Small employers and own account workers; (5) Lower supervisory and technical; (6) Semiroutine; (7) Routine; and (8) Never worked and long-term unemployed.
