The former head of green finance at Hong Kong Exchanges & Clearing (0388) has filed a case to the Labour Tribunal seeking compensation from the bourse.
The case comes amid HKEX losing two heads leading its green and sustainability initiatives in recent weeks, adding to the its turnover as Hong Kong sees a drain in financial talent.
Grace Hui Suk-han, who in January left the bourse just 20 months in the position, filed a case against the firm, which is scheduled to be heard today.
A former UBS executive, Hui was chief operating officer at the exchange's listing department before taking over as head of the green initiative.
The news came as HKEX said in an emailed statement that the head of group strategy Till Rosar and co-head of emerging business development Julien Martin are leaving to pursue interests outside the company, the company.
Glenda So, co-head of markets, is leading HKEX's sustainability and climate-related efforts, a spokesperson said.
HKEX has been striving to turn the city into a sustainability-focused financial hub, competing against Singapore. Chief executive Nicolas Aguzin said in February that the company is experiencing higher staff turnover due to a growing talent war and Covid restrictions, while the city's market and banking regulators said they are facing trouble retaining staff.
Despite the talent loss, the HKEX also brought on 11 new managing directors over the last year to beef up its leadership pool, the spokesperson added.
Meanwhile, Aguzin yesterday said companies have a more urgent need to respond to investor concerns as the pandemic and geopolitical instability lead to a more volatile market.
The comments were made at the launch of IR Connect, a new digital investor relations platform that helps Hong Kong-listed issuers build connectivity and regular dialogue with their stakeholders.
