I am generally in agreement with all of those answers which say, "Don't do this." And, I am generally in agreement with many of the reasons provided by those answers, which basically amount to "this is off-topic", "this is political", etc.
Although, an issue close to your heart can seem pretty non-political to you. And, you may see other people do such things, and seem to get away with it. So, how can you know whether this is appropriate or not?
I will quickly share with you the one time that I did something like this, and seem to have gotten away with it well. I was a college instructor, and I E-Mailed the entire staff at the college inviting them to a service at my church. I ended up receiving no feedback except a few people thanking me for the E-Mail. However, this wasn't just a case of "I have my religious views, and they are important to me, and so I will convince people to obtain what I believe are true beliefs." There was more to the story. The other relevant parts to the story are:
- This was done shortly (maybe 3-4 weeks) after the Boston Marathon bombing on April 15, 2013. This stunned the nation, leaving many people to seek some answers about life (a bit similar to that happening after the twin towers fell on September 11, 2001). Some people may be interested in seeking some sort of healing. There was a (temporary) widespread increase in interest in checking out church services.
- The pastor of my church was a very popular speaker.
- The pastor of my church said he intended to talk about the Boston Marathon bombing.
- When preaching, my pastor has frequently mentioned his hobby of running.
- He was actually a participant in the Boston Marathon on the day that the bombing occurred.
That last bullet point is the only reason I dared write the E-Mail I did. We lived on the opposite side of the continent, and yet I knew of an upcoming rare event of an actual surviving participant being able to give his first-hand story of the attack. (And it ended up being a more interesting story than expected... his wife also ran in the marathon, and the bomb blew up between them, and they quickly each figured out that their pre-arranged plans on where and when to re-unite were ruined.)
If you know of some information that I am unlikely to be able to get from any other source, then many people may not see this as entirely inappropriate. (They might roll their eyes a bit, but may be rather unlikely to be too concerned and/or complain too much). Some examples might be:
- an invitation from you to an event you are personally hosting, like a birthday party for your child (but not a commercial money-making event where you are hoping for sales)
- if you are organizing a group sale, e.g. bulk-rate discounted tickets for a state-wide sports team's game
Realize that even in these cases, some people may disapprove and roll their eyes for being rather off-topic. However, regarding the topics you wrote:
What is this a strike for? If this is a strike at your place of work, then some people may consider this somewhat relevant. If it is a strike for a school district and you're organization is not related to education, then this seems off-topic.
the recent UN report about climate change with some links in order to raise their attention about the topics.
If your organization is not directly involved with climate (or something very related, like "air quality"), then this is likely quite off-topic.
Giving people off-topic news "in order to raise their attention about the topics" sounds quite off-topic. I think a lot of people would have this attitude:
"If I wanted to learn about such an issue, I could check out news reports or find such information myself. If you wish to evangelize about such a topic, please only consider risking such damage to our relationship during off-time. Don't use work resources, which I am required to view to get my job done at work, to promote your own agenda."
