Weak Ties, Strong Doors: Why Casual Connections Matter
2 min read
Close colleagues and friends matter deeply, but many new opportunities travel through lighter connections: former classmates, event acquaintances, or someone you met on a single project.
The surprising strength of weak ties
Sociologist Mark Granovetter’s well-known research in the 1970s found that people often hear about new jobs through acquaintances rather than close friends. The reason is simple: your close circle tends to know the same people and information you already do. Weak ties connect you to different teams, industries and ideas, which makes them a valuable source of fresh perspectives and unexpected opportunities.
Keeping casual connections warm
Weak ties do not need constant attention, but they do benefit from occasional, light contact. The goal is to stay familiar, not to stay in touch every week.
- Congratulate people on new roles, launches or milestones with a short, personal note.
- Share an article or event that connects to something they once mentioned.
- Send a brief check-in two or three times a year to people you enjoyed working with.
- Offer help first, whether an introduction, a recommendation or a quick perspective on a question they shared.
Reconnecting without awkwardness
It is natural to hesitate before messaging someone after a long silence. Acknowledge the gap simply and move on: mention how you know each other, share a brief update, and ask a genuine question about their work. Most people are pleased to hear from a former colleague, especially when the message is sincere and asks for very little.
Build breadth on purpose
Make a small habit of meeting people slightly outside your usual circle, such as another department, a neighbouring industry or a local community event. Over time, these connections widen what you see and who sees you, and that is often where the most interesting career doors begin to open.
