When a Colleague You’re Close To Leaves

Notice what their departure changes for you

A work friendship can live in ordinary moments: lunch downstairs, a shared joke before a meeting, or someone who understands why a particular afternoon was difficult. Their departure may leave gaps that are less visible than an empty desk.

Ask yourself what you are missing most. Is it companionship, reassurance, practical knowledge, or feeling understood? Naming the gap gives you something more specific to respond to than “work feels different now”.

HealthHub’s guidance on transitions explains that change can disrupt routines and feelings of familiarity and security. You can recognise that disruption without judging yourself for finding the change difficult.

Make room for a goodbye and realistic contact

A goodbye need not involve a large gathering or an expensive gift. A brief note, coffee, or sincere thank-you can acknowledge what the friendship has meant to you. Respect their preference if they would rather keep their departure quiet.

You might say: “I’ve really appreciated having you here, especially our lunchtime chats. I’d like to stay in touch. Would you be open to coffee sometime after you’ve settled in?”

An invitation leaves room for their answer. Avoid treating a casual “we must catch up” as an agreed schedule, or assuming the same daily messaging will continue. Ask which personal contact channel they are comfortable using, rather than relying on workplace accounts after they leave.

If their availability changes, you can feel disappointed without immediately deciding that the friendship was never genuine.

Give your working day a little new structure

Start with the part of the day that feels most noticeably different. If you always ate together, decide what you will do for your next lunch break. That might be a walk, a meal with another colleague, or time somewhere away from your desk.

The NHS recommends routine and manageable, short-term steps when coping with change. You do not need to rebuild your entire social life in a week.

• Keep one familiar routine that still works for you.
• Make one low-pressure invitation, such as asking a teammate to join you for lunch.
• Reconnect with someone outside work instead of expecting the office to meet every social need.

Other colleagues do not have to become immediate close friends. MindSG’s advice on supporting colleagues highlights everyday gestures such as checking in and spending time together. Let new connections develop at their own pace, without comparing everyone with the person who left.

Separate missing them from questions about work cover

You may also be worried about what happens to their responsibilities. Keep those questions distinct from the emotional change so that each can receive the right kind of attention.

Ask your manager who will own particular tasks, where to find necessary information, and whom to approach for decisions. For example: “Once Priya leaves, who should I contact about the monthly report?”

For the personal side, speak with someone you trust about how the change feels. Your former colleague should not have to remain an unofficial help desk for the friendship to continue. Follow your organisation’s confidentiality rules when staying in touch.

An illustrative example

This is a fictional situation, not a client account.

After his regular lunch companion leaves, Daniel notices that he spends each break scrolling through their old messages. He misses their company, but he is also unsure who can answer project questions.

He asks his manager to clarify the new contact person. Separately, he sends his friend one invitation to meet outside work. While waiting for a reply, he plans a lunchtime walk and joins another teammate for lunch later that week. He still misses his friend; he has simply made the next few days less uncertain.
