Management T.C. - abbreviation or initials? Hello there, I have this link to a business memo sample and I'd like to know if "T.C." is a common abbreviation in business language (maybe some kind of "coordinator"?) or if it's the writer's initials https://www.englishclub.com/business-english/correspondence-memo.htm Thanks in advance!Oh, and what does "T. B. A" stand for?
