The place I currently work at has got this culture of ignoring developers.

Deadlines get made by 3rd parties and project managers who don't have the technical nounce or experience of our system to make a call on deadlines.

Demos of products are arranged without a discussion with developers as to whether said component will be ready on that date.

3rd parties make decisions about future architecture, offer to assist, then disappear for days on end, to only come back and make out as though they've not been holding us up.

Upper management take no interest, don't listen to the people they pay to do a job.

Currently just moved a PHP web app into a multi tenant scalable EBS environment, but apparently it's not worth asking our view on technical aspects of the business before the shit hits the fan.

Lies to clients about documentation and policies, for example, claims from Sales we have a DR and BCP plan, client called is out, they sent a 2 paragraph A4 document to the client claiming it was our DR and BCP plan without talking to anyone technical, including myself who has years of DR experience. Embarrassing.

Could go on, but rant over.

Setting up the meeting agenda in an accessible place (the same doc used for every recurring meeting which is accessible by everyone in the team) and having the calendar invite that goes to their emails... And guess what?
Those SCABBY NUMPTIES still find a way not to see the fucking video conference link (or sort out their calendar, they are freaking CS grads) and then proceed to spend at least half the meeting (and often showing up late) not having a clue what was expected of them...
YA DIMWIT!! EVERYTHING IS IN THE SAME DOCUMENT, AND YET YOU DIDN'T KNEW WHAT TASKS YOU HAD TO DO BEFORE, INCLUDING THE ONES YOU WERE TOLD TO DO WEEKS AGO???

They all have a BSc in CS (one of which has a MSc) and yet shit like this happens occasionally.

And that happened several times.
