Case Studies

Client Profile

GSK (GlaxoSmithKline) is one of the world’s leading pharmaceutical and healthcare companies, with a commitment to innovation, science, and improving health outcomes globally. The Ware production site in Hertfordshire is a key manufacturing hub, responsible for the production of critical medicines and treatments.

The site’s success depends not only on operational excellence but also on strong, resilient leadership at the local level. GSK recognised the importance of developing its people managers to foster high-performing teams, enhance collaboration, and ensure a culture of continuous improvement and safety.

Challenge

At the Ware site, a small but pivotal management team of eight was facing several challenges. As the production environment became more demanding, the team needed to enhance its approach to performance management, conflict resolution, and communication to ensure consistent leadership.

There was also a broader desire to build authentic leadership behaviours, encourage open feedback, and create a stronger sense of psychological safety and accountability within their teams. Leaders needed the tools and confidence to coach effectively, manage difficult conversations, and model the culture they wanted to embed.

Solution

Rostrup designed and delivered a tailored, in-person 4-module management development programme, specifically for the Ware management team. Each module was highly practical, with exercises and discussions anchored in the real day-to-day challenges of leading in a production environment. Key topics included:

• Conflict Resolution – Tools and techniques for managing tension constructively and proactively
• Performance Management – Setting clear expectations, accountability, and support
• Authenticity & Feedback – Leading with integrity and holding honest, growth-focused conversations
• Coaching & Psychological Safety – Creating an environment where team members feel safe, heard, and empowered

The sessions were spaced out over six months to allow for application between modules and included peer reflection and action planning.

Outcome

The programme significantly enhanced the leadership cohesion and capability of the Ware management team. Managers reported greater confidence in tackling performance issues, resolving conflict, and coaching team members effectively. The focus on authenticity and psychological safety led to stronger team relationships and a more open, trusting environment.

Crucially, the training helped shift the team’s mindset from reactive problem-solving to proactive people leadership, setting a strong foundation for sustained cultural and operational improvements at the site.
