Developing Communication Skills at Work: Speak, Write and Listen So Work Moves
Practical workplace communication: writing chat messages, updating your manager, listening properly and raising hard topics, with example sentences you can reuse.
You post in the team LINE group: "Hi, is that file ready?" and wait all afternoon. In the end you learn your colleague had no idea which file you meant. Half a day lost to one sentence. This is not about anyone being lazy. It is communication missing key information, and it can be trained.
What are workplace communication skills?
The ability to make the other person understand the same thing you do and act on it right away, using as little of both people's time as possible. It is not about being a smooth talker. Good communicators usually write short, ask directly and listen to the end.
1. Write messages people can answer in one go
Most work today happens over LINE, Slack, Teams or email. A good message can be answered without a follow-up question.
The formula: context + request + deadline
- Context: what this is about, which file or project
- Request: what you need the other person to do: approve, review or send something
- Deadline and reason: when you need it and why
Example: instead of "is that file ready?", write "Hi, could I have the latest Q3 sales summary slides? I need them for tomorrow's 10 am client deck. If you can send them by 3 pm today, that would be great."
One message, one topic
If you have three things, number them 1, 2, 3 or send separate messages. People answer more completely, and it is easier to search later.
2. Update your manager in three lines
Most managers do not want every detail. They want to know where the work stands and whether they need to help. Use this structure every time.
- Status: done / in progress / blocked
- Risk: what could slow it down
- Ask: what you need them to decide or help with
Example: "Next month's campaign: brief is done, creative delivers Thursday. Risk: legal has not replied about the promo wording. Could you help chase Khun A?"
If there is bad news, share it early with the options you have already thought through. Your manager will remember that you flagged it, not that something slipped.
3. Listen to understand, not to reply
Play it back before you start
After taking on a task, say: "Let me check I have this right: you want a report comparing sales across the two branches, focused on the new products, due this Friday?" One sentence can stop a lot of work going in the wrong direction.
Ask questions that invite detail
- "If this goes well, what does it look like?"
- "Is there anything you definitely do not want to happen?"
- "Who else needs to see this before it goes out?"
4. Raise hard topics without damaging the relationship
Hard topics include turning down extra work, telling a teammate their work is late, or disagreeing with your manager. Thai workplace culture often avoids directness, but silence usually lets problems grow.
Talk about behaviour and impact, not the person
Instead of "you are always late", try: "The last two reports reached me a day after we agreed, so I could not send them to the client on time. Is something blocking you? Where can I help?"
Say no with options
"This week I have A and B due. If I take on C, B may move to Monday. How would you like me to prioritise?" You are not refusing. You are giving your manager the full picture to decide.
What to avoid
- Sending "are you free?" without saying what it is about. The other person waits without knowing how urgent it is.
- Long arguments in group chats. If it is not settled after three messages, book a short call.
- Using team jargon with people outside your team. Abbreviations you know well can easily be misread.
Good communication does not mean saying more. It means the other person never has to ask you back.
How to start this week
- Look at your last five work messages. Check whether each has context, a request and a deadline.
- Send your manager a three-line update every Friday, even if they did not ask.
- Play back every new task you receive for at least one week.
- Pick one hard conversation you have been putting off, write your opening line using behaviour and impact, and book the talk.
