Practicing Grammar

Good business writing doesn’t permit the use of excessive passive verbs. The passive voice is used in situations where you don’t want to attribute the action to a particular person or group. As a general rule, you should use few passive verbs in your writing. That said, passive constructions are quite appropriate in situations where the reader doesn’t need to know who performed the action.
