Neil Robson Discusses FCA Non-Financial Misconduct Regime With Law360

Law360 recently spoke with Financial Markets and Funds Partner Neil Robson regarding the FCA’s new rules on non-financial misconduct, which take effect this week and will hold some 37,000 non-banking finance businesses, including asset managers and insurers, to the same conduct standards already in place for banks, targeting bullying, harassment, and violence at work. Lawyers have warned that the regime could unfairly jeopardize careers, as firms face both wider enforcement risk and a temptation toward excessive caution in hiring decisions and regulatory references. Read about Neil’s comments.


Broader FCA Regulatory Reference Rules Leave Newer Market Entrants ‘Highly Vulnerable’

Law360 recently spoke with Financial Markets and Funds Partner Neil Robson regarding the FCA’s extension of non-financial misconduct rules to 37,000 non-bank firms, which, since 1 September, have been required to provide more detail about non-financial misconduct in regulatory references. Legal experts warn that the wider requirements are likely to spur a surge in disputes between firms and former employees, as bullying, harassment and discrimination are often more subjective and fact-sensitive than financial misconduct. Read about Neil’s warning for newer market entrants.
