What does this sound like?
Encourage public service managers and employees to communicate openly with the public about policies, programs, services and initiatives they are familiar with and for which they have responsibility. Openness in government promotes accessibility and accountability. It enables informed public participation in the formulation of policy, ensures fairness in decision making, and enables the public to assess performance. An open and democratic government implies that all employees have a role in communicating with the public while respecting the constitution and laws of Canada. Public service managers and employees must respect privacy rights, matters before the courts, national security, Cabinet confidences and ministerial responsibility. They serve the public interest best by communicating openly and responsively about policies, programs, services and initiatives they help to administer, while treating sensitive information with the discretion it requires.
A strong rationale for government bureaucrats to widely adopt social media communications, perhaps? (Complete with caveats about doing so responsibly). Surprise — it comes from the Communications Policy of the Government of Canada.
Interesting: it looks like this has been part of the communications policy from at least 2002. Well before most of us had any idea about blogging, web 2.0 or social media. Go ahead, take a look at the text of the archived 2002 policy statement, it says the same thing.
(The GoC Communications Policy is a bit of a laundry list of requirements — 31 in total — for various aspects of communications: advertising, publishing, web, crisis communications, media relations, corporate identity, and so on. It’s easy to get lost in the details of each of these requirements and forget the overarching principles, laid out in the policy statement at the front end of the document. I’ve often skipped past this section — usually b/c I’m looking for some specific detail buried deeper in the document. But the other day I re-read the policy statement again for the first time in a long while, and that’s when this jumped out at me.)
