Entrepreneurs' Days : Meet a coach: préserver mon capital santé en tant que dirigeant

À propos de ce webinar

Le capital santé des dirigeants est le premier actif immatériel de la PME. » Torres, 2012

Après une carrière professionnelle dans le monde industriel où il a géré des équipes de 300 personnes, Tom a constaté l’importance du lien et de la communication au sein des équipes. Il décide début 2016 de se recentrer sur l’aspect humain et développe à son compte un service centré sur la cohésion de groupe et le développement d’organisations puis rejoint, en tant qu’actionnaire, la société « Pétillances sàrl » un organisme de formation continue dédié à la prévention des risques psychosociaux et au développement des compétences personnelles via une approche pédagogique aussi humaniste que systémique.

Tom partagera avec vous des cas pratiques qu’il a rencontrés dans son parcours d’employé puis de dirigeant et les approches qui ont été utilisés pour faire émerger une solution.

En tant que dirigeants, quels en sont les bénéfices ?

  • Sensibilisation au risque de santé du dirigeant et son impact sur l’entreprise
  • Travail sur les réflexes du dirigeant
  • Auto check : testez-vous !
