Growing up, one piece of workplace advice my parents taught me is to never use contractions in any form of professional writing (resumes, cover letters, email correspondence, etc.).
I've been told that instead of using contractions like it's, can't, wouldn't, and shouldn't, I should use it is, can not, would not, and should not.
Is using contractions really discouraged? Are there any scenarios where contractions can be used in professional writing? Or should contractions always be avoided?
