Do your colleagues read the emails or they ignore them like mine?
The usual answer is: sorry no time to read, place a meeting.

I do not want to schedule yet another useless meeting because you are unable to read two lines of text.
If I wanted a meeting I would have scheduled it in first place.
Why have I to lose 1 hour of my time to explain, then some cannot join and ask for a follow up meeting, where I have to explain again the same things.

Obviously during the first meeting nobody has even read the description and has idea of the topic, so "we need to check... schedule another meeting next week".

You can imagine what's gonna happen the next week...

A couple of weeks ago my manager asked me to stay in the office for 3 hours more (after a full 8 hours there) because he had to go to a client and
1. I'm doing an interim + thesis for my graduation in that company so I'm not a real employee there
2. I did that project because it was slightly related to my thesis
3. Nobody else was available due to another project (he, the same manager, hasn't assigned the roles for weeks and now everybody has to work overtime because it's late)
4. I had an exam the following week
5. He should have gone after lunch and asked me to be available in that time frame but he disappeared and came back at the end of the day

I literally escaped with "I've an exam next week and I'm gonna miss the bus. Bye bye"
