III: Press Releаse: Develоp а press releаse using the fоllоwing email and template below: Email starts here Thanks for moving on this press release. We should have had this out much earlier, but that's on neither of us. We have a comfortable estimate that thousands of people will be walking in Pittsburgh at our 2026 Pittsburgh Autism Speaks Walk (June 5th at Schenley Park in Oakland has been confirmed). Please put “right in the heart of Pittsburgh” somewhere. We also need to emphasize that their dollars help to fund advocacy, awareness, family services and critical research. As you know, we're cutting many of the smaller walks in the outlying counties this year, so we need to address this as well. Maybe out of common courtesy, business ethics, and just being human, we should have reached out to these areas first, but it's too late for that now, so they'll have to find out via this press release. Walks pulling in less than $100,000 were cut—let's not put that to press, but we need to explain that one large Walk cuts down on the operating costs of hosting smaller Walks (including website maintenance, printed materials, kickoffs and awards, etc.). Maybe say something like “we concluded that it makes more sense to give back within smaller communities to ensure that we are being true to our mission, and making the best use of the dollars you all have worked so hard to raise” and just include some of those costs I mentioned above. We expect that the individual teams will complain about not being able to come to Pittsburgh, and we certainly still want them to raise money, so maybe head this off with “We certainly understand that for many, travel will be a barrier. If that is the case, your fundraising dollars can be managed through online donations on your personal Walk webpage, or mailed to the Western PA Chapter.” Also throw this in: “Over time, we will schedule town halls, sensory fairs, and other family services and community events that will give your community the individualized support you need from us.” This will buy us some time until we actually do these things, pending costs, of course. Personally, all these sound more expensive than maintaining local annual Walks and focusing on awareness, but who am I?We can't forget about fundraising materials! We've spent a lot of money on these so let's use them! Please include: “Once you sign up your team at www.autismspeakswalk.org/pittsburgh, you can fill out the online request form. We can send you puzzle pieces, posters – whatever you need!” Thanks for arranging this and getting our name out there! End of email Template: Contact Information: [Company] [Contact Name]

I. Prоblemаtic Emаil: Reаd the email belоw, then identify 4 issues with it. Tо: All Staff From: Russ Tagart Subject: Rick is Sick Beginning next Monday, Rick Halred will be taking medical leave, so please wish him the best as you see him this week. Rick easily has been the best worker in our office, and I have a great card ready for you to sign and to contribute, but for those who miss this, I'll just sign your name and give on your behalf (you can pay me back next pay). As some of you know, Rick is also going through a divorce as well, so I hope that factors into your giving. Btw, with Rick gone indefinitely, his duties will fall onto Suzie and Dale. Any questions (including from Suzie and Dale), please see Rick before his end of day on Friday. Russ Tagart Regional Director “No shirt, no shoes, and I still get service” Redfoo 4ever There are at least five issues with this email, in your own words, note four. 1. 2. 3. 4. Please note that none of the issues have to do with spelling, punctuation, spacing, etc. All the issues have to do with liability, appropriateness, and effectiveness. The task is only asking to identify the issues, not offer solutions, but feel free to also offer solutions/alternatives if you like.
