In work English, some messages can be very short, and some need full sentences. The difference is not grammar for its own sake. It is clarity and respect.
Chat with your team
Short is fine, if it is clear.
Call moved to 3 pm.
Email to a client
Use full sentences. A client should not have to guess.
I am writing to confirm that the call has moved to 3 pm.
Bad news
Always use full sentences, and be kind.
I am sorry, but we need two more days.
Instructions
Number the steps, and use full sentences for anything important.
- Open the file. 2. Check the price.
When unsure, write more
A clear full sentence is never wrong. A short message can be.
Grammar matters most in writing
In chat, small mistakes are normal. In a client email, check the important lines.
Words to remember
- clarity — being easy to understand
- confirm — to say something is fixed
- instruction — words that tell you what to do
- guess — to answer without being sure
Questions & answers
Q: Can I write "thx" to my boss?
Only if your boss writes like that. Otherwise, write "thank you".
Q: Is a full stop rude in chat?
A single full stop can feel cold. In email, full stops are normal.
Q: How short is too short?
If the reader must ask "what do you mean?", it is too short.
Q: Should I use full grammar in chat?
Clear words matter more than perfect grammar. But do not write "cl 3" for a client.
Q: What about voice messages at work?
Ask first. Some people cannot listen in an open office.
