There is no necessary and direct causal relationship between birthplace and work performance and style, and the work performance and style of employees cannot be accurately predicted based solely on birthplace. Work performance and style are affected by a combination of many complex factors, including personal education background, professional experience, personality traits, values, skill level, training received, and the culture of the team and organization. People from different birthplaces may have some cultural commonalities, but individual differences are huge. Employees from the same birthplace will show a variety of performance and styles at work, and they cannot be generalized. To understand the work performance and style of employees, it is more reliable to communicate with employees directly, observe their work behavior, evaluate their work results, refer to their performance feedback, and other actual work scenarios.
