Is the preposition “from” optional for “resign”?

Question

I have visited Google Ngram for “resign from” and “resign”. I found out that the use of “resign” alone is more common than “resign from”.

Does this mean that the preposition from becomes more optional?
If it doesn't, which of these two sentences is more correct using the verb resign?

1. I resigned from the position as worker of Fishy Company.
2. I resigned the position as worker of Fishy Company.

Answer 1

In American English, it depends on context. When speaking of a job or title, 'from' is optional. The following are equivalent:

• I resigned from my senate seat.
• I resigned my senate seat.

But when the thing being resigned from is a collective body, 'from' is required.

• I resigned from the legislature.
• I resigned from Fishy Corporation.

Answer 2

Yes, resign can take a direct object

He resigned his post.

or a preposition-phrase complement

He resigned from his position.

Answer 3

Traditionally it is to resign from a post. Occasionally a prepositon after a verb can be dropped in the course of time. But Google Ngrams shows to resign from is the preferred construction.
