The Quiet Cost of Not Speaking Up

A lack of assertiveness can stop you from getting your needs met, damaging your mental health and relationships. And for organisations, assertiveness isn't just an individual personality trait - it's key to a successful, productive workforce:

55%

Missed Opportunities

Of employees believe they have missed out on promotions or pay rises due to a lack of assertiveness.

79%

Under-35s Affected

Of younger workers feel they lack the confidence to speak up in meetings or advocate for their ideas.

81%

Self-Taught Gap

Of the workforce struggle with assertiveness, yet only 4% have ever received formal training to bridge the gap.

How A Lack Of Assertiveness Holds You Back

Not knowing how to behave and communicate assertively can show up in subtle but damaging ways. When you don't feel empowered to speak up, you might:

Say A Resentful "Yes"

You say an automatic 'yes' to requests without checking your own capacity, leading to resentment, exhaustion and burnout.

Stay Silent In Meetings

Your brilliant ideas or important concerns are left unshared because you don't feel confident, or you're worried about being perceived as 'difficult'.

Be Continuously Overlooked

Your fear of speaking up or asking for what you want holds you back from achieving career or academic opportunities, and personal goals.

Struggle With Self-Esteem

You don't stand up for yourself, which reinforces the subconscious belief that your opinions and needs don't matter, eroding your self-worth and confidence.

The good news? Assertiveness is a communication skill that you can learn, not just a personality trait you're born with. Let me show you how.

What The Assertiveness Training Course Covers

No ‘Death by PowerPoint’! Fun, engaging workshops packed with tools to use the very next day.

1. What Gets In The Way Of Assertiveness?

We'll explore the psychology behind our fears of assertiveness, including the 'fawn' response, and the myth that assertiveness is the same as being 'aggressive'.

The Result: You'll understand why you stay silent, and why assertiveness is actually kinder than passivity.

2. Assertiveness Tools, Techniques + Strategies

Master 'I' statements, the art of understanding and stating your needs, how to hold your physical and vocal space in any situation - and much more.

The Result: Practical tips and frameworks to make sure you're heard and respected.

3. Learn Boundaries That Raise Self-Esteem

Learn therapist-backed techniques to start saying 'no', and set boundaries that protect your capacity, your time, and your mental wellbeing.

The Result: Greater self-worth and self-confidence as you know how to set and express your limits.

Not at all. It's for anyone who wants to learn how to communicate with more confidence, from those who struggle to speak up, to leaders who want to make sure their impact matches their intent.
