chronemics and deadlines
Chronemics refers to the role of time in communication. The two basic orientations are monochronic and polychronic.
Monochronic cultures, such as in the USA, time is linear. Output is prioritized so, wrapping up projects and punctuality are important. You may hear phrases like, "time is money," and "Early is on time. On time is late" in monochronic environments.
Polychronic engages in many things at one time. With juggling so many balls, deadlines are flexible and breaks are welcomed. Think "Island time" and "mañana, mañana" mentality.
