How does Google, a global company, manage punctuality and reliability across different time zones in its teams?

Yes, GitLab is a notable example of a company that has successfully implemented core work hours for employees in different time zones. GitLab operates on a remote-first model and has employees spread across various time zones worldwide. They have established 'overlap hours' where all employees are expected to be available, promoting cross-regional collaboration and effective communication.

Some alternative strategies to promote cross-regional collaboration and effective communication in global companies like Tesla could include: implementing a robust digital communication platform that supports real-time collaboration; organizing regular virtual team meetings to keep everyone updated; creating a culture of open communication where employees feel comfortable sharing ideas and feedback; providing training on effective communication and collaboration techniques; and establishing clear expectations and guidelines for communication. It's also important to consider time zones and to schedule meetings at times that are convenient for all team members.
