Questions & Answers about На работе я принимаю важные решения спокойно.
Because на работе is the normal Russian expression for at work.
Even though English uses at, Russian often uses на with places connected to activities or institutions. So:
- на работе = at work
- на уроке = in class / at the lesson
- на заводе = at the factory
В работе usually means something different, more like in the work/process or in operation/use, not simply at work as a location or situation.
Работе is in the prepositional case.
The phrase на работе uses на + prepositional when talking about being at a place. The dictionary form is работа, and in the prepositional singular it becomes:
- работа
- на работе
So the -е ending shows that case.
