The world's largest chipmaker promised to create thousands of US jobs. There are growing tensions over whether US workers have the skills or work ethic to do them.

• TSMC says the opening of its Arizona factory has been delayed over a shortage of skilled workers.
• Differences in US and Taiwanese work culture could pose another challenge.
• Some TSMC workers are doubtful that Americans can adjust to the challenging work environment.

The world's leading chipmaker says a lack of skills among American workers is why the opening of its Phoenix semiconductor factory has been pushed back to 2025.
