Don't let this gap widen
Failing to master assertiveness exposes you to frequent relational blocks in the company.
Studies show that 65% of professional conflicts stem from inadequate communication, resulting in an estimated 20% productivity loss per year.
Careers stagnate when assertive skills are missing with colleagues or clients.
Acting now prevents these concrete risks and secures your professional progression.
Participants explore the foundations of assertiveness through personal diagnostics and self-assessment tools. Practical exercises help identify passive or aggressive behaviors. Concrete company cases illustrate the impacts. Deliverables include an individual progress plan and observation grids.
Focus on assertive formulation methods with filmed role-playing scenarios. Learners use adapted scripts and receive structured feedback. Varied professional examples reinforce learning. Deliverables include a repertoire of standard phrases and a daily practice journal.
Deep dive into conflict management through assertiveness with collaborative workshops. Tools such as negotiation cards and priority matrices are applied to real scenarios. Participants produce case analyses and personalized strategies by the end of the day.
Integration of assertiveness into leadership roles through meeting simulations. Assertive feedback and delegation methods are tested. Concrete company cases enable the development of collective action plans. Deliverables include an assertive leadership guide and tracking indicators.
Synthesis of acquired skills with presentation of individual projects to the group. Impact measurement tools and company deployment plans are finalized. A final certifying assessment validates competencies. Deliverables include a complete portfolio and a post-training implementation commitment.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
