While employment in Britain is at record levels, there is widespread concern many jobs are not of sufficient quality to maintain a healthy and thriving society. Growing public concern culminated in the government commissioning the 'Good work: The Taylor Review of Modern Working Practices' in 2017. A key recommendation of the Taylor Review was that the government should adopt a multidimensional definition of 'good work', among other recommendations. Building upon decades of academic research demonstrating their relationship with job-related wellbeing, the Taylor Review identified six dimensions as central to 'good work' (DBEIS 2017: 12) (wages, employment quality, education and training, working conditions, work-life balance, and consultative participation/collective representation). The overall objective of this SDAI project is to explore an occupational approach to mapping, understanding, and improving the quality of working life by applying insights from sociological theories of stratification which suggest that the capacity to achieve high job-related wellbeing is to a large extent determined by occupation-field of work. However, this issue has been scarcely researched. The extent to which job quality and job-related wellbeing are structured across the occupational structure are critical issues to understanding and developing pathways to improving the quality of working life, for instance, through occupational mobility or workplace practices that might moderate the effect of occupational environment. We propose creating a new Classification of Occupational Quality (COQ) for this purpose. This is because existing occupational classifications (such as the NS-SEC occupational class schema used by the ONS) were not intended to map job quality defined in a multidimensional way, and as such tended to focus on only a single job quality dimension. A more appropriate tool for the current academic and policy context is necessary. Moreover, the sparse existing research findings suggest that dimensions of job quality and measures of job-related wellbeing do not neatly map onto occupational classes in any case. The specific research questions motivating this proposal are: 1. What is the structure of 'occupational quality'? 2. How does occupational quality influence individuals' subjective wellbeing over the life course? 3. Is mobility across occupational quality structure an effective means of improving the quality of working life? 4. To what extent does the workplace moderate the effect of occupational quality on job quality and wellbeing? Using existing ESRC data, we will answer these questions through writing-up and submitting the results to four world-class academic journals. Emerging findings will be shared at, and feedback will be gathered from a range of national and international conferences, as well as specialist workshops with targeted academic experts to ensure maximum academic impact. A distinctive part of our SDAI project is its impact strategy beyond academia. With the support of the Dept BEIS (the department responsible for implementing the government's job quality strategy) and the CIPD (the professional body of the HR profession who have been a leading voice in the job quality debate), we will channel our findings to policy and practitioner audiences (see Letter of Support). This includes a series of policy and practitioner workshops, as well as plain English briefings of our research outputs, to be hosted on the project website (www.qualityofworkinglife.org). We will also enlist a design agency to prepare searchable and graphical presentations of occupational quality data we will produce from ESRC data. The project website will also host short video factuals which we will produce, summarising each paper. Collectively, these strategies will ensure maximum impact at a time when the issue of job quality has never been so pressing as well as maximising return on existing ESRC investments.
