Final answer:
Geocentric Staffing is the model that treats PCNs, HCNs, and TCNs equally, selecting the best individual for a position regardless of nationality.
Step-by-step explanation:
The staffing model that puts Parent-Country Nationals (PCNs), Host-Country Nationals (HCNs), and Third-Country Nationals (TCNs) on an equal footing is Geocentric Staffing. This approach does not prioritize one group over another. Instead, the best individual for a job is selected regardless of nationality.
The ethos behind this model is that it can create a strong culture of unity and cooperation, aligning with the organization's global strategy.
On the contrary, Ethnocentric Staffing prioritizes individuals from the parent country, while Polycentric Staffing involves hiring host country nationals for positions in their own country, and Regiocentric Staffing limits recruitment to specific regions.
