All of the academic editing that I do is in the American Psychological Association (APA) style. I know the manual inside and out and have memorized page numbers for most rules. On page 99, you will find a list thirty-nine common suffixes and prefixes that APA doesn't hyphenate before and after, except in certain situations.
Some words will absolutely need a hyphen to avoid confusion and misunderstanding. Sometimes the editor will need to ask for clarity; other times, the meaning will be apparent.
For example, should it be re-pair or repair? The spelling depends on the author's intention: to pair again or to fix.
Should it be re-sign or resign? Depends whether the writer means to sign again. Or does the writer mean to give up or relinquish?
Would it be re-form or reform?
Would it be un-ionized or unionized?
For writers, it's helpful to have an understanding of possible confusion due to hyphens, especially if you don't plan to hire an editor!
