When addressing others in a discussion/presentation make sure you are engaging in a dialogue rather than delivering a speech.

2. Don’t talk at people,
talk to them
When addressing others in a discussion/presentation make sure you
are engaging in a dialogue rather than delivering a speech. Give other
a chance to speak and encourage them to ask questions and share
their views.

3. Don’t
interrupt
Basic etiquette dictates not to interrupt people while they are speaking.
If you have a point to make, it is wise to wait for you turn. When you
interrupt someone mid-sentence you might miss out on something
valuable the other person might have said.

4. Don’t
bad mouth others
You might not always be on the best terms with some of your co-
workers and/or bosses. However, be wary of gossiping about them.
Rumours always get around faster and could end up creating
uncomfortable situations. Build bridges instead of burning them.

5. Don’t
use profane language
Some of us tend to use foul language more often than we’d like to.
Don’t let your anger and resentment show through the words you use.
Employers highly value professional decorum so it is best to keep your
language clean to maintain a good impression.

6. Don’t
blow your own trumpet
Tempting as it may be, don’t speak excessively about your own
achievements. Instead of talking about your accomplishments to
others, you could, at relevant moments speak about how your work has
helped achieve a particular goal or target. By doing so you will adding
value to their time.
