Again, I'm going to have to state that I had the complete opposite experience with DialogueDirect, and I also worked in their Portland office. I also feel it’s necessary to point out the tone of your report is one of extreme anger and negativity, so if that’s the attitude you brought to the job? It's no wonder you got fired on your first day hun. You described potential sponsors as being "b*tchy" and complained about the weather, I remember those being big no no's of the job.
I also remember there being a "no negativity" rule, and you described yourself as frustrated and stressed on more than one occasion in your report. Now don't get me wrong, I got frustrated many times while fundraising for DialogueDirect, but my outward appearance and the way I spoke to people, never reflected the way I was feeling inside. You? If someone actually stopped to buy you a smoothie, and team managers complained about you then obviously you were displaying some emotions or attitudes that would lead a reasonable person to believe you were being negative or to the "smoothie buyer"...having a tough day.
DialogueDirect had a saying about the weather conditions, I think it was "who cares, those kids live in worse conditions than we can ever imagine." In your report you attempt to induce sympathy because Portland gets hot, so does sub-saharan Africa, know what I mean? I'm sure you were told that this was an outdoor job at the interview, and that you would receive lots of rejection, so why were you surprised by the people "blowing you off"? Or the "108 degree weather"?
Anyway, I agree with them that if you were that negative, which your own report indicates anger and negativity, then you weren’t worth keeping around past that day. Hey, you're lucky you got one day, I've seen jobs were super negative people were fired at training. Negativity spreads through a team environment like a wildfire or a bad virus, so I hope there is a lesson in this.
