Objectives: To identify core and cross-time workplace hazards and worker's exposure prevention profile towards outbreaks in three non-healthcare work settings; to evaluate effectiveness of a theory-based educational programme on improving attitude to vaccination and virus testing in workplace; to longitudinally compare attitude of willingness to vaccination, testing of SARS-CoV-2 and changes of risk profile toward outbreaks among workers. Design: A 5-year study comprising a randomized controlled trial (RCT) and 3 parallel longitudinal studies with baseline and follow-up repeated measurements. Setting: Non-office, mobile and office work settings. Participants: Part I is a RCT, 294 workers will be randomised to an intervention group (a theory-based education programme) and a control group with measurements repeated at 3rd, 6th and 9th month. Part II is a longitudinal quantitative study (i.e., prospective cohort study) involving 1,495 workers recruited at the baseline and followed up for 2 years. Part III is a longitudinal qualitative study involving 26 management and frontline workers. Part IV is a longitudinal workplace hygiene study involving 6 workplaces enrolled at the baseline and followed up to conduct ventilation investigation. Intervention: Theory-based education intervention to build positive attitude of control measures towards SARS-CoV-2 outbreak. Main outcome measure: Workplace hygiene data (airflow, air volume, etc.); willingness to vaccination and virus tests; actual uptake of SARS-CoV-2 antibody testing. Data analyses: Multivariate regression logistic model and thematically analysed will be performed for quantitative and qualitative analysis. Intention-to-treat analysis will be employed for RCT. Expected results: Large dataset of longitudinal measurement of willingness to vaccination/testing and actual uptake will be documented to inform policy. Educational intervention will be developed to mitigate risks of outbreaks in workplace.
