It’s a tool. Use it or don’t use it
The people I work for instituted instant messaging (specifically Microsoft Lync) a couple of years ago. The IT guys are smitten by it but I couldn’t care less. I would prefer face~to~face conversation, or a telephone call, or at least an email that keeps a record (I don’t care WHAT Lois Lerner says ;’)
Recently our management team announced that IM was the “wave of the future” and demanded that we use it. They loaded it onto every computer in the company. So I have it installed, enabled, and signed in but minimized to the desktop. As far as anyone is concerned I am an active participant but I sure do miss a lot of “phone calls” LOL
