Many times each week I get asked for guidance in relation to multi forward published by others while on business time. Because it is a company e-mail does that mean they not any longer own it? Because an e-mail is written on business time, does not negate copyright and common courtesy.
Should you copy the original sender and ask when it is O.K. before forwarding their e-mail? Ccing doesnt negate requesting permission. E-mails are sent and written towards the party where they were intended, regardless of when or where they may be written and are to not be brought to others with no senders permission first. Period or risk the effects.
Now, as everyone knows, there has to be no expectation of privacy online. But that doesnt mean anything goes or that business courtesy is thrown out the window!
You can be putting your organization in legal jeopardy in the event you forward outside the company and you can be putting your reputation as a professional at risk by forwarding internally. In running a business, copyright issues are much more at play and every responsible company needs to have an insurance plan on what can and ought to be forwarded and just how via e-mail.
Common courtesy dictates you may not forward without the original senders knowledge. They can not appreciate the e-mail they wrote for you being delivered to those they dont know. Or they mult1forward not mind by any means. So just ask!
Certainly it will go without stating that while on company time the forwarding of shall we simply say anything questionable content-wise (NSF = Unsafe for Work) or perhaps not business related simply ought not to be forwarded whatsoever. Save those e-mails for your personal account while on personal time.
For additional, I actually have a write-up with a few extra general forwarding tips that affect business and private e-mails alike that you could find helpful: 5 Rules for Forwarding. Why not also take a look at my Copyright Refresher while you are at it?
