5 Informal Ways to say “Former Colleague”

When you’re chatting with friends or in less formal settings, you might prefer to use a more laid-back term to talk about people you used to work with.

Here are some casual alternatives you can throw into everyday conversations when talking about a former colleague.

Ex-coworker

For someone who used to share your workspace but doesn’t anymore, you could call them your ‘ex-coworker’. This term is less formal and great for talking about past jobs with new friends or at casual get-togethers.

You can use ‘ex-coworker’ when catching up with friends or discussing old work experiences in a relaxed setting, like when sharing tales about your previous job or reconnecting with old pals.

Examples:

 “I bumped into my ex-coworker at the supermarket yesterday.”

“My ex-coworker and I used to have the best discussions during lunch breaks.”

“I remember the fun times with my ex-coworker at office parties.”

“My ex-coworker was always full of hilarious stories.”

“My ex-coworker and I still share a lot of inside jokes.”

Ex-colleague

The term ‘ex-colleague’ keeps things simple and light-hearted. It’s an informal way to refer to someone you used to work with, similar to saying “ex-classmate” or “ex-roommate.”

It’s perfect for casual chats, perhaps while reminiscing over a cup of coffee or at a reunion. It’s a breezy term that doesn’t have a formal feel, making it ideal for relaxed, daily conversations.

Examples:

 “I went to a concert with my ex-colleague over the weekend.”

“My ex-colleague and I had some memorable work trips together.”

“I catch up with my ex-colleague every few months for coffee.”

“My ex-colleague was always up for a game of table tennis during breaks.”

“I ran into my ex-colleague at a friend’s wedding.”

Old colleague

Calling someone your ‘old colleague’ adds a bit of sentimentality to your reference. It has a more friendly and affectionate tone, implying a personal bond over time, much like an “old friend.”

Use this term when you want to express a sense of history and familiarity. It’s suitable for laid-back chats, such as catching up with a mutual friend or reminiscing about the “good old days” at a prior job. It’s perfect for relaxed talks with family or friends, or when reminiscing about your past work life.

Examples:

 “I had a great time catching up with an old colleague recently.”

“My old colleague and I used to compete in office quiz competitions.”

“I bumped into my old colleague during a vacation.”

“I often reminisce about the fun times with my old colleague.”

“My old colleague sent me a thoughtful gift for my birthday.”

Old partner

The term ‘old partner’ has a friendly, informal vibe, suggesting that you and the person in question once worked together on projects or business ventures. It conveys a sense of camaraderie and a shared journey, making it a warm, casual alternative to ‘former colleague’.

It’s a good substitute for “former colleague” when you want to emphasize the teamwork aspect of your past relationship. Use ‘old partner’ when telling tales about joint projects or past successes.

Examples:

 “I met up with my old partner for a game of golf.”

“My old partner and I used to volunteer for corporate social responsibility activities.”

“I attended a book signing event with my old partner.”

“My old partner was always the life of office parties.”

One-time co-worker

“One-time co-worker” is an informal and laid-back way to refer to someone you’ve worked with before. This phrase highlights that you and this person were part of the same workforce, but only for a specific period.

It’s a handy term when you want to clarify that your working relationship with this person was limited to a certain time or project.

Examples:

 “I received a holiday card from a one-time co-worker.”

“My one-time co-worker and I worked on a challenging project together.”

“I had a chance encounter with a one-time co-worker at a seminar.”

“My one-time co-worker and I used to go for runs after work.”

“I shared a cab ride home with a one-time co-worker after a late-night work session.”

In conclusion, whether you’re in a formal or casual setting, there are plenty of ways to refer to your past work relationships beyond just saying ‘former colleague’. From phrases like ‘former associate’ and ‘previous colleague’ for professional contexts, to more relaxed terms such as ‘old partner’ and ‘ex-colleague’ for casual conversations, you have an array of options to choose from. So next time you’re discussing old jobs or reminiscing about past collaborations, try using these alternatives.
