Yes, I know this sounds like a mouthful when you're reading this and that's exactly what it is - a mouthful...of no good.
Sadly, in Christian circles people deceive themselves and call their "tale-bearing" behaviour "burden-sharing" and in the Corporate world it is sometimes referred to as "Networking." Changing the name of a thing/activity does not change what it is...and we all know when we're doing the wrong thing. If you're so sure that you'd repeat whatever you say behind someone's back in their face so why not skip one step and just say it to their face?
In living by it, I've on occassion been "accused" of lacking tact. I'm usually quick to apologize when it is brought to my notice and still say (to myself of course) that: "I'd rather lack tact than join others to attack you - especially when you're not there."
Proverbs 25: 23 - Gossip brings anger just as surely as the north wind brings rain.**
Proverbs 26: 20 -22 - Where there is no wood, the fire goes out; And where there is no talebearer, strife ceases. As charcoal is to burning coals, and wood to fire, So is a contentious man to kindle strife. The words of a talebearer are like tasty trifles, And they go down into the inmost body.***
Please with all the words that come around you, please make sure you are not "adding wood" to any fire. When it comes to talking about others, be a fire-fighter & life saver by extension. If and when all of us truly care for our neighbours and love them as we love ourselves, we'd talk to people rather than about them. If you must talk about people, talk to God about them. If you're not even sure if/when you should talk to them, ask Him and He'll guide you not just on the "when" but also on the "how" to say the "what" you need to say. When we start to look out for each other for their good, from that point, the world will only get better.
