A few times per week I get requested guidance with regards to multi forward written by others while on business time. As it is a company e-mail does that mean they no more own it? Because an e-mail is written on business time, is not going to negate copyright and common courtesy.
In case you copy the original sender and/or ask when it is O.K. before forwarding their e-mail? Ccing doesnt negate asking for permission. E-mails are sent and written to the party where these were intended, regardless of when or where these are written and therefore are never to be shipped to others without having the senders permission first. Period or risk the outcomes.
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 could be putting your company in legal jeopardy when you forward outside of the company and you could be putting your reputation as a professional at risk by forwarding internally. In running a business, copyright issues are even more at play as well as every responsible company must have a policy about what can and must be forwarded and how via e-mail.
Common courtesy dictates you may not forward without having the original senders knowledge. They may not appreciate the e-mail they wrote for your needs being sent to those they dont know. Or they mult1forward not mind at all. So just ask!
Certainly it must go without stating that throughout company time the forwarding of shall we just say anything questionable content-wise (NSF = Not Safe for Work) or otherwise not business related simply should not be forwarded by any means. Save those e-mails for your personal personal account throughout personal time.
