3PB's employment and discrimination barristers Karen Moss and Mark Green (pictured here) have co-authored ‘A Practical Guide to Age Discrimination in the Workplace’ which is now available from Law Brief Publishing and legal booksellers.

An essential companion for practitioners and litigants-in-person involved in age discrimination claims before the employment tribunal, the book demystifies the legal framework and provides practical guidance. From defining comparators to understanding where to pitch injury to feelings awards, and from drafting pleadings to the use of statistics, every chapter offers hands-on advice grounded in experience and statutory guidance. The book also includes discussion of thorny age-related topics such as retirement, menopause and workplace banter.

Karen's notable cases include acting as lead counsel representing over 50 senior cabin crew in a group action against an international airline relating to a mass redundancy exercise which was found to be unfair.
