In professional communication, messages like "LOL ;)" and "PLZ" are considered?

In professional communication, the use of abbreviations and emoticons like "LOL ;)" or "PLZ" is often categorized as informal. This form of communication is typically more relaxed and personal, which does not align with the expectations of professionalism in most workplace settings.

Formality is a key component in professional communication, where clarity, respect, and professionalism are prioritized. Using casual language or text-speak can give an impression of familiarity that may not be suitable in formal communications, such as emails, reports, or presentations.

Although some environments may tolerate an informal tone, it is generally advisable to maintain a level of professionalism and avoid terms or phrases that can be perceived as too casual. Thus, the characterization of these types of messages as informal is fitting, emphasizing the need for appropriate language that reflects the nature of the professional environment.
