Don't use idioms and words you are unsure about. Stay within your comfort zone if vocabulary and express yourself clearly. Don't use ambiguous words, phrases or sentence structures.
Etiquette is your image builder. Your work comes first and foremost but your self id comes a close second. Be professional and confident to look your co workers in the eyes and greet them at the start and end of each day.
Be polite. Smartphones are a tool, an appendage. Do not treat them as excuses to avoid eye contact. Keep them on silent and check them when you step out for a tea or coffee break. Emergencies are what your co workers and seniors are there for. If it's a genuine crisis, the image you have cultivated will form the basis of the response from your colleagues.
