Many times weekly I have asked for guidance with regards to multi forward authored by others throughout business time. Since it is an organization e-mail does that mean they no more own it? Because an e-mail is written on business time, does not negate copyright and common courtesy.
Should you copy the initial sender or 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 for which these people were intended, no matter what when or where they can be written and they are to never be brought to others minus the senders permission first. Period or risk the results.
Now, we all know, there must be no expectation of privacy online. But that doesnt mean anything goes or that business courtesy is thrown out your window!
You might be putting your organization in legal jeopardy should you forward away from company and you can be putting your reputation as a professional on the line by forwarding internally. Running a business, copyright issues are a lot more at play and each and every responsible company ought to have a plan on which can and really should be forwarded and just how via e-mail.
Common courtesy dictates you do not forward minus 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 should go without saying that throughout company time the forwarding of shall we say anything questionable content-wise (NSF = Unsafe for Work) or not business related simply really should not be forwarded by any means. Save those e-mails for the personal account throughout personal time.
