Improving atmosphere
It might be a very small thing, but when you let basic standards of civility slip it doesn't bode well for the future.
You'll find a simple "good morning" goes a long way to improving communication and fostering a good atmosphere in the long run.
It makes your colleagues human
You need to view the people you work with as flesh-and-blood people and not shadowy figures you resent.
This will come in handy later when you're trying to solve problems and collaborate.
It makes your workplace democratic
If everyone says good morning, no matter what their rank, if means that everyone from the managing director to the cleaner is treated with the same importance.
It's a marker of how you feel about your workplace
A greeting at the beginning of the day is quick, free and painless or at least it should be.
If you find the mere act of saying hello difficult, then it could be a warning sign that it's time to look for a new job.
Everyone wants recognition
This simple act will make your colleagues feel value as you're showing them recognition, and most people want to be recognised whether they realise it consciously or not.
It's also a way of making your presence felt rather than skulking in and slinking into your chair.
A greeting blows away awkwardness
If you've not bothered to say hello, imagine how tricky it's going to be later in the day when you need to speak to your colleague about a problem or ask for their help.
Start the day on a good note, and you'll rule out potentially stressful situations later in the day.
