Strong Workplace Cultures Are Built by Leaders Who Show Up During Crisis

In this episode of The High Performance Herd, David Quick sits down with John Oswald, President and CEO of Mills Manufacturing, to discuss the leadership required to sustain a defence manufacturing culture through crisis, regulatory demands, and the realities of managing a diverse, multilingual workforce.

John was raised by a single mother and assumed significant household responsibilities from an early age. His path into leadership developed through circumstance, mentorship, and experience, from captaining a youth hockey team to leading Mills Manufacturing, a company operating under strict military compliance standards. He guided the organisation through its designation as an essential operation during the COVID-19 pandemic and through the disruption caused by Hurricane Helene, when normal communications were unavailable for nine days and 130 of 150 employees returned to support the business and one another.

As he explains in this conversation, the strength of workplace culture becomes most visible during moments of genuine pressure. Employees decide whether to take responsibility and support their colleagues based on the standards leaders have established beforehand. John argues that organisational friction and confusion often begin with leadership, requiring executives to examine their own behaviour before expecting change from the wider team.

David and John also examine how personal experience and mentorship shape leadership style, the practical demands of managing a multilingual workforce, and the role employee referrals play in recruitment within a specialised industry. Their discussion covers employee empowerment, communication, performance indicators, board oversight, and the consistent application of core values. They also consider the strategic importance of establishing a minimum revenue floor to improve stability and prepare the company for future opportunities.

For leaders in manufacturing, defence, and other compliance-driven sectors, as well as founders managing diverse teams, this episode offers a grounded perspective on what sustains a workforce through disruption. It is a practical account of how leadership presence, organisational trust, and strategic clarity help hold a business together when normal operating conditions no longer apply.
