For a coworker~4 min · 201 words

I want to start by saying how wonderful Alex looks today — which, if you knew them at nineteen, is genuinely worth a round of applause.

I'm Sam, Alex's coworker, and I've had the front-row seat for most of the good stuff.

I met Alex across a desk, and within a week I knew two things: Alex was far too good at the job, and far too kind to hold it over the rest of us. Work friends are one thing. Alex became just... friend.

So let me switch gears for a second, because there's something I really do want to say.

Marriage teaches you loyalty, patience, and understanding. Which means Alex had absolutely none of these before they met Jordan.

When two people are right for each other, you can feel it in the room, and every one of us felt it the moment they walked in today.

And then Jordan came along. I've never seen Alex happier or more themselves — steadier, softer, quicker to laugh. Jordan, you are so obviously the one.

So whether you came for Alex, for Jordan, or purely for the buffet, please raise your glass to the two of them. To Alex and Jordan.

The structure that works

  1. 1Open with a hook — a one-line joke or a striking line, not 'for those who don't know me'
  2. 2Introduce who you are and how you know the groom
  3. 3One vivid, true story that captures who the groom really is
  4. 4A warm, gentle roast that the whole room (and his mum) can enjoy
  5. 5The turn: how he changed when he met his partner
  6. 6Genuine praise for the couple together
  7. 7A toast the room can raise a glass to

Frequently asked questions

How long should a best man speech for your coworker be?+

Three to five minutes — roughly 400 to 650 words. Long enough for one good story about your coworker and a heartfelt turn, short enough that nobody's drink goes warm. If in doubt, aim for four.

How do you start a best man speech for a coworker?+

Skip "for those who don't know me". Open with something specific to your coworker — a one-line image, a gentle tease, or a promise. For example: "I've known Alex long enough to have plenty of stories, and I love them enough to have chosen the kind ones. Mostly."

What should you not say in a best man speech for a coworker?+

Don't deliver a performance review or list their achievements like a reference Don't drown the room in industry jargon or inside office politics Don't share anything confidential or professionally awkward

How do I make office anecdotes land with people who don't work there?+

Translate everything. Cut acronyms, explain roles in one line, and choose universal stakes — a deadline, a crisis, a client from hell — that anyone can feel. Skip inside politics entirely. Frame each anecdote around a human trait the whole room will recognise in Alex. If a guest's grandparent couldn't follow it, simplify until they could.

I mostly know them from work — can I still be the best man or maid of honour?+

Yes, plenty of close friendships start at work. Own your angle: you've seen a side of Alex the family hasn't. Build on the moments your relationship crossed from professional to personal, and be honest that the office is where it began. Ask their partner or old friends for one story outside work to round out the picture.

How do I give a work-based speech that isn't boring?+

Ban the CV. No one wants a list of achievements. Instead, pick one story where Alex's real character showed under pressure — the kindness, the calm, the humour — and tell it like a friend, not a manager. Strip the jargon so everyone follows. The office is just your setting; the person is your subject. Aim to reveal them, not review them.
