"Public Relations" According to Ap Style

Who knew that the term 'public relations' had so many rules according to the AP Stylebook? I am here to fill you in on what this coveted handbook has to say about the term 'public relations:'

• The term public relations should be lowercase in all situations.  The P is capitalized only when it is at the beginning of a sentence.
• Spell out public relations in first references.  The abbreviation PR is acceptable in second references. 
• In the abbreviation PR, use capitals without periods or a hyphen.  
• Public relations is always singular (be careful when you spell check!).
• PR is never used as a verb.
• Public relations workers are practitioners.  Alternatively, say PR professionals, workers, etc. Never use perjoratives unless it is in direct quotes.
