Reconnect with five people before you need them

A simple exercise to warm up your network over a month, so it's there when you need it

Over a month, send a short, warm note to five people from past jobs, one at a time, asking for nothing.

  • 8 steps
  • You and five people
  • Once a year
  • Sequence

Why this can work

The time to reconnect with people is when you don't need anything, because that's when a note is simply nice to get. Former colleagues who've moved on see openings, teams and changes you can't see from where you sit. Five notes over a month means that if you ever do need help, you're picking up a conversation rather than starting one.

You’ll come away with five relationships warmer than they were, and a few conversations started.

Making it work for you

Every workplace is different. Here’s what to think about before you start, and what might get in the way.

Things to think about

Ask what they're working on and whether there's anything you could help with. The relationships that last are the ones where both people give.

What might make this harder

Skip those people this round. Start with people who'd be glad to hear from you; there's no prize for difficulty.

Questions people ask

How do I reconnect with former coworkers?

Send a short note that mentions something you shared, asks what they're up to, and asks for nothing.

What should I say to someone I haven't talked to in years?

Acknowledge the gap, mention a specific memory or something that made you think of them, and ask how they're doing. Keep it short enough to answer easily.

Why do weak ties matter for finding a job?

Acquaintances tend to move in different circles than your close friends, so they hear about openings and ideas you wouldn't. That's the idea behind the phrase the strength of weak ties.

Is it okay to reconnect with people because I might need them later?

Yes, as long as the note itself asks for nothing and the interest is real. Wanting a warm network is sensible, and the other person still gets a genuine hello.

The longer read

Why this works, and where it comes from

Networks cool down quietly. You change jobs, people scatter, and colleagues you once saw every day become names you mean to write to. A network is much easier to use when it's already warm. A note to someone you've kept in touch with starts a conversation; a note after five silent years reads as a request.

Former colleagues matter for a reason that's been studied. In a well-known 1973 paper, The Strength of Weak Ties, the sociologist Mark Granovetter argued that acquaintances are often more useful than close friends for hearing about new jobs and ideas, because they move in different circles and know things your inner circle doesn't. People from past jobs are exactly those ties: scattered across companies, teams and industries, each with a view you can't get from where you sit.

Truest's version turns that idea into a month with a shape. Five people, one at a time, chosen for range rather than importance, each note asking for nothing. Spacing them out keeps it light enough to finish. Choosing for range is what makes weak ties worth having.

If you've just lost your job and need work now, skip the slow warm-up. Write to people directly, say what happened and what you're looking for, and ask for specific help. People tend to respond well to a clear, honest ask from someone they remember kindly, and a month of gentle notes is a luxury you can skip.
