Don't let this gap widen
Entrepreneurs who neglect assertiveness lose up to 40 percent of their funding opportunities according to recent studies.
This weakness leads to failed negotiations and reduced credibility with partners.
Over the long term, it slows company growth and limits career advancement for freelancers.
Acting now prevents these issues and secures market positioning.
Participants explore the fundamentals of assertiveness through practical role-playing exercises, analyses of real cases from the startup and freelance world, as well as tools like the DESC method and constructive feedback. They work on contract negotiation and client conflict management scenarios to produce a personalized action plan at the end of the day.
The Training Assertiveness - Strengthening Your Professional Impact program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.
