At the beginning of each week, think about two or three people you would like to reach out to, Mallick said. It doesn't have to be a video meeting if you have screen fatigue — you can send someone a text or a brief email to say hello. If you see an article that reminds you of that person, send it to them or consider sharing it and tagging them on LinkedIn, she said.
Also, look for opportunities to collaborate with employees you normally wouldn't work with. "What you want to do is be part of the collaboration, meet new people, and then get new people into your network who you can call after the fact and have other conversations with," said Teresa White, president of Aflac Inc., in Columbus, GA.
