Pros

• Strong narrative and ambition around growth, especially at the top • Well-defined frameworks that look robust on paper • A small number of genuinely strong leaders who uphold standards and push for real accountability

Cons

• The “Associates” concept is not consistently lived—many employees feel more used than valued • Contributions are often not recognised; high performers can feel invisible unless they actively self-promote • Management is aware of engagement and morale issues but action is slow or superficial • Casual racism and bias exist in parts of the organisation and are often tolerated or ignored rather than addressed directly • Inclusion is talked about more than it is enforced in day-to-day behaviours • Career development is weak and inconsistent. • Opportunities are not always merit-based; favoritism and internal networks play a significant role in who gets visibility and advancement • Accountability is low—leaders are comfortable leading discussions but avoid owning outcomes • Missed commitments rarely have consequences, which lowers the overall performance bar • Decision-making is slow, political, and often happens offline; formal forums are sometimes just for alignment, not real decisions • Governance is selectively followed—processes are bypassed when inconvenient!! • A culture of “chasing” is normalized—teams spend excessive time following up instead of executing • Strong individuals are relied upon to hold things together; when they leave, performance drops • Leadership frequently pushes ambitious targets without taking full ownership of operational realities, creating downstream pressure on teams • There is a tendency to label those who uphold standards and governance as “difficult” or “inflexible,” instead of addressing underlying gaps • Constructive challenge is sometimes dismissed or redirected, creating a perception that speaking up carries more risk than staying aligned • At times, leadership narratives can shift to suit the situation, which can feel like a dismissal of earlier positions or agreed principles • Associates who push for discipline and accountability may feel their intent is mischaracterised rather than genuinely considered

Pros

I’ve been at Mars (Yorkville site) for about three months as a Quality Systems Senior Specialist, and so far it’s been a great experience. Everyone has been genuinely friendly, welcoming, and willing to help. The culture feels very supportive—people want to see you succeed and are quick to share knowledge and offer guidance. My manager has been amazing and is truly invested in my growth. She’s helped set clear expectations, encouraged development, and provided the tools and support I need to be successful.

Cons

None so far—still new, but my experience has been very positive.
