The document discusses emerging flexible workplace models that are challenging traditional office environments. These models include co-working spaces, which allow individuals from different companies to work collaboratively in shared office spaces. Pro-working allows companies to make underutilized office space available to business partners. On-demand space options like LiquidSpace offer temporary office space that can be booked online. Hub and spoke and office club models provide a mix of centralized headquarters and smaller satellite offices located closer to employees. These new flexible models are driven by an increasingly mobile workforce and offer cost savings and improved employee experiences over traditional offices.
