What's going on at JPM?

Recognize that JPM has always been sweaty, but what's been going on recently? Hearing that every group right now is near breaking-point in terms of analyst morale. Assuming it's largely due to the laughable / insulting bonuses for A1s? Or is something going on with personnel? 

Any other detail would be helpful / interesting...hearing that even groups that used to have good culture (i.e. HC / tech) have been brutal this summer in terms of hours, culture, etc.
