As an expert in Human Resources, she held various positions in two international companies from 2004 to 2015. Recognized and appreciated as a “business partner”, she worked closely with management, executives and their teams in different countries in Europe. In particular, she participated in the creation of a company in Switzerland and the implementation of its Human Resources department.

Based on her life experience, her passion for human relations and guided by her values of openness, listening, authenticity and empathy, Corinne Emonet has chosen a career in individual and team support. The focus is mainly on organizational and professional aspects and leadership development.

In 2016, Corinne Emonet started working with the PTO Association and Wejobshare Sàrl as a coach and facilitator of various workshops, conferences and meetings on the topic of jobs and topsharing in Western Switzerland. Promoting and implementing job sharing as an innovative work model in companies is a mission that is in line with her values.

With courage, optimism and resilience, Corinne Emonet meets life’s challenges with great adaptability. She combines energy, structure and sensitivity in her various activities. She likes to question herself and it is important to her to develop her inner garden, cultivating harmony, well-being and performance in her roles as mother, professional and woman.

2021 was a year of deep questioning. A new path has opened up, that of independence, allowing her to become a “slasher” and thus pursue the various activities that fascinate her.

Nina Prochazka has been actively dealing with different work models for years and knows the topic of job and top sharing from different perspectives. For PTO, she works as a coach, conducts workshops and moderates networking events.

In addition, she works as a consultant at B’VM, a management consultancy specializing in nonprofit organizations. Her focus areas include change management and transformation, agile structures and self-organization, collaboration, knowledge management, and new work environments.

Urs Stauffer has more than 20 years of international experience in human resources management, having held various specialist and management positions. His focus is on supporting organizations and executives in matters relating to modern collaboration, shared leadership (job and top sharing), skills development, and healthy and sustainable leadership.

As a certified coach, trainer, and mediator, he combines methodological depth with practical implementation – structured, people-centered, and with a keen sense of dynamics.

Urs Stauffer had his first and very formative experience with shared leadership in top sharing at cinfo with Irenka Krone, co-founder of Go4Jobsharing. This collaboration impressively demonstrated how shared leadership – based on trust, mutual sparring, and the conscious contribution of different perspectives – not only leads to personal relief, but also promotes collective clarity and strength, with tangible added value for the team and the entire organization.

In 2023, he and his wife founded Introspecto GmbH, a consulting firm for personnel and organizational development, which they manage using the top sharing model.

Since 2026, Urs Stauffer has been an active member and expert of the PTO association.

She spent her teenage years in French-speaking Switzerland before moving to the United Kingdom, where she graduated from Oxford Brookes University.

Adrian Marti is a Senior Consultant at cinfo in the field of international cooperation (recruitment and coaching) and Director of Elora Finance Sàrl, active in the field of sustainable investments and innovative development finance. Adrian Marti is also an active coach within the PTO with job or topsharing duos.

Adrian Marti has over 25 years of experience in international management, including 18 years overseas, mostly in transition countries. His experience spans the non-profit, government and private sectors.

Work-life balance has been a personal and professional thread for the last 20 years.

Professionally, he has coached hundreds of international managers on these topics, including the possibility of job and top sharing. This has helped managers make important decisions to adjust their careers, better know what they want, and negotiate with superiors/institutions to achieve their goals.

Privately, he has worked to support a family system in which both partners work internationally and raise three children. This revealed that a maximum 160% work schedule for both was an optimal system for the family with young children. This led to a successful four-year job share as Deputy Country Director in India for Swiss Development Cooperation (SDC). A. Marti also advised his partner on how to transform a department head position in the Swiss Foreign Ministry into a successful topsharing with her deputy that allowed her to be more present at home.

The relevance of job/topsharing will become even more important in a post-covid environment with a greater need to manage one’s career and ambitions.

A. Martis Hintergrund liegt in den Bereichen Management, Finanzen, Personalwesen und Evaluierung. Er hat zwei Masters (HEC Lausanne & Graduate Institute Genf). Er ist auch ein zertifizierter Trigon Coach.
