Are there people that actually want to dispatch from home?
Putting aside the health concerns with COVID, the ADF isn't wrong. You lose almost all DRM when you're at home.
Think about how often you or someone else in the office is having an issue. In almost all scenarios, people come to their desk and help them thru the problem. If you're aircraft is in an emergency, you won't have time to call people and get assistance. Sometimes that ability to yell across the room and have everyone surround you and support you immediately is paramount to our job. Anyone who has ever been on a conference call knows just how useless people can be over the phone and how difficult it can be to explain a situation over the phone. Add to that the fact that being at home adds more distractions, especially people with kids! Imagine if you will you're on the SAT Phone with an aircraft that has declared and emergency and needs your assistance with finding a safe place to land... then suddenly your kids comes in the room yelling about how His brother hit him and yada yada yada.... This is what kids do. It doesn't matter if Mommy or Daddy said they can't go in there, they are kids. They will still go in that room. These are distractions that you just can't have as someone with operational control.
I'm not a fan of long term dispatching from home. I believe an argument can be made for a temporary solution if your office is suffering from COVID, but otherwise I don't personally think it would be a wise choice for the industry. With our jobs come a lot of responsibility. Unlike most jobs, we can't always step away from it when we are needed elsewhere.
