Head offices are mostly at a certain distance from cubicles. It is essential to maintain certain behaviors during official hours and also when you are within the office environment.
Don’t use regional languages:
You should avoid talking to team members in group meetings in your regional languages as the others (one who doesn’t belong to same region) might feel excluded
Be sure with communication:
In most of the MNC companies employees interact with each other over emails, video conferencing and chats. So make sure you are expressing yourself very well in terms of your ideas to team members
