Unrecognized bads or costs: Sceptics also point to ‘bads’ or costs associated with work that tend to go unrecognized. The most obvious of these is the opportunity costs resulting from the amount of time spent working. Typically, full-time workers spend 1,500–2,500 hours per year on the job, equivalent to around nine to fifteen weeks annually. These are hours that, were they not allocated to working, could be devoted to leisure, sleep, exercise, family life, civic and community engagement, and so on (Rose 2016). These hours do not include the considerable amount of time that workers expend on training or educating themselves for work or on commuting to and from workplaces. Nor does it include the hours that many salaried workers are expected to be ‘connected’ or ‘on call’ by their employers. Formal employment also tends to preclude workers from work other than that performed for their employers, with the result that workers often end up paying other workers for that labor. Such costs include the hiring of housekeepers, child care providers, maintenance experts and landscapers, etc. And while unemployment seems to have adverse effects on our physical and mental well-being, working is not free of adverse health effects either, including stress, emotional frustration, and physical ailments from repetitive work tasks or ergonomic deficiencies in workplace design.
