Guys, you are definitely making too much rumour about this video. Watch it once again, cool down. I can see that:
1. there is some management' clown in a funny baseball hat walking all over the room and disturbing operational staff
2. all the people who are walking behind and making photos are obviously at their breaks and don't work at the moment
3. 1/3 - 1/2 of people in front of the screens don't even turn their heads around to see what's going on, they remain perfectly calm and focused on their screens
4. most of the remaining stay plugged and seated, paying attention to their screens, just turning their heads for a moment to see what's going on
5. only one guy sitting next to the board does unplug and stand up, but he might have been working at some quiet sector (even in Spain at the moment not every sector is at 110% capacity all the time), or doing some non-ATC work at the moment, just utilizing the station, i.e. for maintenance
6. sometimes a friend walking behind, tapping you at the shoulder just to say 'hello' is more disturbing to operational work than whole this situation
7. if you are from Britain, you'll never fully understand why people from Spain express themselves by shouting and whistling. It's just a cultural difference. Spaniards don't have any idea why do you eat this crappy English food as well.
