Just to point out, no company pays an employee 100-150k CAD to watch YT.
What tends to happen, and I've been in that situation, is goals keep getting shifted and priorities changed with a lot of "re-organising" within the company and by re-org I mean from one month to the next those employees find themselves in new teams with new priorities and new responsibilities that are themselves not very well defined.
As a result, management has a hard time assigning work given a lack of priorities and clear goal. Leaving employees with a lot of time to "figure out" what they need to work on.
Some employees will self-manage and start doing stuff on their own. This rarely works to their advantage because eventually a manager will pipe up and go "Who asked you to do this".
Not to say employees are blameless. If a company is so mis-managed it cannot give you a goal and priorities to work on, just leave.
But OTOH some employees will see that mis-management then look at their paycheck and go "Nah this is fine".
As an example, Star Citizen. 700M+ in crowd funding. No game(s). Horror stories from every ex-employee about micro-management - eg Change this pixel to green.
I think development hell from the lack of direction is quite common in the gaming industry. For example FF15 was in development hell for like 7 years with no game being made except a bunch of cool concept videos, due to Nomura has no direction. Then SE kicked Nomura out of the team and get Hajime Tabata to save this project and made it into a totally different game. The end result still suffered though.
Unknown 9 likely experienced the same thing.
That being said, employee's action at work is mostly just working attitude sort of thing. If there are no tasks, people could study work related subjects instead of drinking beer. I can probably tolerate people chatting during breaks, MAYBE watch YouTube video as long as it is work skill related videos.
I am
probably okay with people playing table tennis or have party after 6pm-7pm too....
Drinking beer in early afternoon is more ridiculous and it does look bad imo. If I am a manager of an office, I would definitely try to stop this kind of culture from spreading in the work environment.
