Gillian MacLellan is a partner in our UK Employment Team working with clients in varied sectors across the UK advising on both contentious employment matters and transactional work; the common thread in both areas is her ability and determination to get a great result for her client. Gillian does a huge amount in the financial services and energy sectors and key current areas of focus include advising on whistleblowing, harassment and business change exercises, as well as on sector specific issues such as the SMCR.

Gillian currently chairs CBI Scotland's People & Skills Forum and is a regular speaker at conferences and an author for LexisNexis and XpertHR.
