I personally feel that social media and e-communication (e-mail, texting, etc.) have destroyed the communication chain.
If this media could be used in a way where something could be posted and checked (and it actually happens), then it COULD be great. From my experience, the excessive use of e-mails, texts, tweets, etc. has become a cop-out. All too often I see people sending out a mass e-mail with zero follow-up. When something goes amiss, it is too easy to blame the recipient for not being at a desk all day.
I often say that social media has been the death of being social. In my short three years in the Army, I have seen the exact same thing here. It is too easy to send an e-mail, text, or tweet (which may or may not be received) and expect results. This often backfires.
The simple act of doing a quick round and getting in some face time not only guarantees that the message will be received, but it also boosts morale. To me, direction coming from a person speaks far greater volume than that read on a screen.
At one time we had party lines, pay phones and teletype and as change happened, society changed along with it. Social sites have a way of connecting people but there is that risk of harassment and other things. Personally employers have no right to snoop. It is online voyeurism and detrimental in building trust.
In other words, employers should not spy and neither should anyone else. Intelligence Agencies have a vested interest in rooting out dangerous subversives so I get that.
