In case you're wondering what my first experience at Sociological Perspectives was like:
All R&Rs, no matter how much work needs to be done, must be returned within 60 days. The editor is sometimes willing to give you a 3 or 4 day extension, and that's it.
The reviewers (I had) are micromanagers who want to rewrite the paper for you, and in at least one case, will forget what they told you to do the last time.
