Final answer:
The incorrect statement about workplace messaging is that the use of emojis and informal language is acceptable. Messages should be professional, without the use of emojis or informal language, and include proper spelling and grammar, with a record kept for documentation.
Step-by-step explanation:
With respect to workplace use of messaging, the statement that 'Use of emojis and informal language is acceptable' is incorrect. In a professional setting, messages should always be clear and professional. Emojis and informal language can be seen as unprofessional and might weaken the intended message. Furthermore, any confidential information should be handled with care and not be shared inappropriately. When messaging within a professional context, you should use correct spelling, proper grammar, and maintain a professional tone. It's also imperative that all messages are saved for documentation, as they can serve as proof of communication and might be important for future reference. It's common practice to adhere to basic communication practices like responding promptly to emails and messages, and using respectful language, tailored to maintain professional communication and etiquette.
