Cory is a software engineer at a large tech company. He is working on a team with several other engineers to develop a new product. One of his team members, Jack, is consistently missing deadlines and not pulling his weight. Cory has tried to talk to him about it several times, but he has been dismissive and has not changed his behavior.$$

What is the best way to handle this situation?

Alert the manager to the issue and let them handle it$.$

Hope that it resolves itself on its own and ignore the issue.

Confront Jack directly and tell him that he needs to improve his performance, or he will report him to his manager.

Try to talk to Jack again in a private setting and see if they can work together to find a solution.
