Yes, communication on paper or face-to-face is a safer option than communicating electronically through email or texting. There are so many times that we hear about emails being leaked to the press. We should communicate in person as much as possible so no one can hack into our computers and read our conversations.
it is essential for organisations to recognize the importance of employee communication and the appropriate use of communication channels in employee communication. The choice of communication media use in employee communication is important. Organisations can choose to communicate either face-to-face or through various forms of mediated communications. The selection of communication tools are based on how effective they are in achieving the bottom-line of the business goal and how they fit in a strategic internal communication process.
If they're not using any sort of electronic communication they're probably afraid of getting caught doing something illegal. I don't trust any bankers after the whole economic collapse that happened a few years back with the housing market. They see what Hillary Clinton is going through with her Emails and don't want that to happen to them.
It is understandable that some bankers may be disinclined to use electronic forms of communication because they fear they could be hacked. However, only conducting business face-to-face in this day and age is totally unrealistic. Additionally, it makes sharing information and keeping records much more difficult and much less reliable.
