Since joining the bank only months before recession began to loom in 2007, Risley has overseen the integration of Halifax Bank of Scotland (HBOS) and Lloyds, established 1,000 senior executive appointments, upgraded talent management, leadership development and succession and supported staff through major organisational change and restructuring.
Risley formulated a robust reward governance framework, ?improved HR processes, service delivery and management information - and managed all this with "tighter controls, improved risk management and reduced costs".
But in February, she lost her direct link to group chief executive, António Horta-Osório, after a restructure meaning the HR, legal and audit departments were merged into a single 'corporate functions' division. Horta-Osório reduced his direct reports from 14 to 10, creating a new group corporate functions director, to whom Risley was set to report.
At the time, LBG told HR that rather than reduce the influence of HR in the business, the changes had been designed to strengthen it.
Horta-Osório, who in 2011 took a leave of absence, citing extreme exhaustion, said: "By creating a group corporate functions director, we will be able to bring better focus on areas such as HR, legal, secretariat and group audit."
LBG was awarded a 2012 HR Excellence Award for its L&D strategy, following the launch of its 14 learning academies, with 26 faculties across the group. It reported 91% of employees have access to the curriculum - and 68% of employees say LBG provides them with the opportunity for L&D, a score 11% higher than the national average. The company has saved £3 million in training since the launch.
Risley told HR: "Leaving Lloyds was a difficult decision, but having completed the integration, I feel this is the right time to move on and consider another group HRD role."
It is understood Rupert McNeil has been appointed as group HRD replacing Risley. He is due to join LBG from Aviva in September.
