This paper is the first to study whether Human Resource Practices (HRP) disclosure in sustainability reports of Financial Services Sector (FSS) firms comply with G3 guidelines. The paper raises issue on compliance of practices with G3 because it is considered as a generally acceptable reporting framework by many organisations around the world and expects firms to provide consistent and comparable information in sustainability reports. To measure compliance it compares HRP disclosure with the disclosure guidelines in G3 and then compliance between firms within a region and between regions, namely: Europe, Asia and 'Others'. Using content analysis the paper measures HRP disclosure compliance with G3 standard disclosures between companies in the financial service sector within region and between regions and (ii) then uses hierarchical regression analysis to investigate the determinants of the compliance level. The paper reveals that the level of compliance with G 3 by FSS firms is higher in Europe than in Asia or the 'Others' region. The regression analysis suggests that region, strength of reporting, ethical behaviour of firm, labour/employer relations and capacity of the firms to innovate are the main explanatory variables of HRP disclosures in the FSS firms. Findings of this study would be useful to potential employees, trade unions as well as national regulators and international organisations such as the International Labour Organisations (ILOs) and the OECD. This study also infers that good corporate communication on HRP maintains good labour/employer relationship
