Here are a few basic etiquette pointers to keep things cool in the workplace:
Do respect your coworker’s space. Offices, even if they are cubicles or open desks, should be respected as belonging to the ‘owner.’ Knock on the cubicle door or otherwise announce yourself and refrain from leaning on someone else’s desk.
Do make work-friends. Some offices everyone is close and others are strictly business-only. Do what works for you, but knowing a few details about co-workers’ lives makes it a lot easier to make small talk in the elevator or while waiting for the coffee to finish brewing.
Do ask before you put someone on speakerphone. If anyone else will be listening to the call, introduce them as well. Likewise if you’d like to record a call, ask first.
