Abstract: This article explores how flattened, team-oriented organizational structures aimed at boosting flexibility, collaboration, and innovation may unintentionally make it harder for women to navigate career opportunities and progression. Through a review of relevant academic literature, the article examines research showing that flattened hierarchies tend to de-emphasize clear career ladders, rely more heavily on informal networks, and reward aggressive self-promotion - all factors that can place women at a systematic disadvantage compared to their male counterparts due to entrenched gender biases and norms. The article then proposes evidence-based strategies for mitigating these deterrents, such as formally defining career lattices, implementing sponsorship programs, providing implicit bias training, and distributing recognition equitably across teams. Case studies of technology companies adopting such practices demonstrate how intentional efforts have yielded success expanding representation while sustaining innovative cultures. The article aims to equip practitioners with research-grounded solutions for broadening opportunities for women within collaborative work structures.
