There is a sort of stress that comes from a "slow-paced environment" where you've got a 50% or less duty cycle of doing real work because you're always waiting for somebody else to do something. Too little work can be just as stressful as too much.
This. Hurry up and wait. That's exactly how it worked for me when I worked for a large company. Need to make a database change? Be prepared to wait 3 weeks unless you can get someone several levels above you on the org chart to take notice. Same for any kind of additional access you might need, or to provision any amount of computing or network resources...
And you know what my department did?
We've managed to setup our own database servers, so changes became independent of any payment system and could be done on the spot.
I know things suck in corporations, but sometimes it's your fault for not doing anything about it.
