Looking at relevant literature I found some papers like Bankers and their bonuses ( Bell and Reenen, 2014) and Gender Pay Gap, Voluntary Interventions and Re- cession: The Case of the British Financial Services Sector (Healy and Ahamed, 2019) which address this issues of disparity in bonuses given to women employees.
Although the former talks about the global recession and how it has affected this issue, it was published in 2014 and as such does not take into account the recent laws that have come into effect in the UK regarding GPG disparity . The latter is a more recent publication but does not take into account the effect of developments
like the Equality Act (2010). Thus further research is required so that we get a better idea as to how the GPG has changed not only before and after recession, but almost 10 years after the recession happened where are we now in terms of pay gap and have the various acts and laws over the years made any real impact in organisations or is the pay gap still a part of most banking cultures.
Who Works for Whom and the UK Gender Pay Gap (Jewell, Razzu and Singleton),
Modelling the gender pay gap in the UK: 1998 to 2006, Women and recession revisited (Rubery and Rafferty), Are female top managers really paid less?(Geiler and Renneboog), The UK Gender Pay Gap 1997–2015: What Is the Role of the Public Sector?(Jones , MakePeace and Wass). These publication look at the gender pay gap in the UK markets not just specifically banks and also look at how developments like recession have had a negative impact on women employment which ultimately lead to unequal pay.Wage Responses to Gender Pay Gap Reporting Requirements (Jack Blundell)
