What is the correct way to write Writers Workshop with or without apostrophe?

The correct way to write "Writers Workshop" is without an apostrophe.

Here's why:

* It's a proper noun: "Writers Workshop" is the name of a specific entity, like a class, program, or event.

* Proper nouns are not possessive: They don't indicate ownership or possession.

Therefore, you wouldn't use an apostrophe in this case.
