In Working Girls, Trixie and Katya dole out both savvy and satirical advice for every stage of working life, from choosing a career path to sailing into a blissful retirement, in step-by-step guides, quizzes, the world's most bizarre aptitude test and more. Trapped in one of the Nine Circles of Retail Hell? Agonising over how to get that raise? Suspicious that your colleague doesn't really hope that their email 'finds you well'? Trixie and Katya have got you covered.

They also share personal stories from their own remarkable careers and their philosophies on everything from office attire to getting fired with dignity, all alongside hilarious, gorgeous photographs.
