So, I'm currently a student in my second year at a business college. So far, I've taken strictly online classes and been put in many group projects.. and I've hated every single one. As a preface, online classes are on 7 week terms, so they are really fast-paced. So, I'm in a project management course right now and we were assigned groups for a 5-week project.

So, I created a slack channel for all of the members to join so that everyone can respond on time and have no excuses. This was created Tuesday afternoon. All throughout today (Wed) they have been joining the channel. I greeted each individual as they joined and only one responded throughout the entire day (we'll call him Member #1). Keep in mind, at midnight tonight (Wed) we have a project due on software we were assigned. I started messaging our Slack group chat at around 7PM and Member #1 was the only one that responded to me for 2 hours. We ended up figuring out everything we had to do and finished the work with no sign of the other group members. Keep in mind, in Slack, when you swipe to the left, you are able to see who is online and physically looking at the chat. I saw the other group members online and looking at the chat multiple times while Member #1 and I were talking. I then asked if they were in the chat and able to respond and got no response. Long story short, Member #1 and I finished our work at around 10PM.

Now that Member #1 and I were done, I filled out an evaluation form for the group that's used for tracking our progress throughout the 5 weeks. I marked the other group members as 0 participation and noted in the spreadsheet that they did not discuss with Member #1 and I about the work even once. I mentioned it's not a huge deal and that I talked to them about it individually in hopes that things will improve in the future. I then messaged the Slack chat and told the non-participating members that I marked them as 0 participation, that it's nothing serious, and that I hope that the communication can improve for the future. I honestly would've waited for them to respond until midnight, but they literally did not say a word to me all day in our group chat in addition to ignoring my message throughout the conversation when I asked them if they were in the chat while I saw they were online.

I personally think I was a little harsh about it, but I also think that it was a solid leadership move to keep them accountable. I asked my dad about it and he said "if I was a 30 year old guy in that class and some young kid was talking to me like that, I wouldn't respond just out of spite." I thought that was an extremely arrogant POV and still warrants them to be kept accountable.

TLDR; college class group members didn't respond once after being in a group chat and watching the conversation while me and another member got the work done. I submitted a review saying they had a zero participation ranking and told them they need to better their communication for the future. AITA?
