Recognize that there may be generational differences in how you should communicate in your organization or workplace. As a new professional and native user of these relatively new forms of communication, you need to be sensitive to such generational differences. Avoid making biased assumptions.
There may also be security or privacy issues related to confidential information. Check with your manager about his or her preference for communicating via text, telephone, or an instant messenger program. Be sure you read and understand any formal policies regarding communication when sensitive or confidential information is involved.
