I think most folks want to care about their jobs and the default is having a healthy level of investment. But especially in larger companies, it’s so easy to get burned by workplace politics or leaders just not seeing things the same way you do — just as you said.

Emotional disinvestment in work is a defensive mechanism. Honestly, it feels like the two camps in this thread are almost talking past each other. Yes, it’s good to be invested in your work — it’s better for your emotional/existential health and good for your career. On the other hand, investment being a net good for an employee is hugely dependent on your work environment.

While one could argue that the right thing to do if you feel you can’t be invested is to leave, and I generally agree that leaving is the only real long-term solution, there are also a million reasons why it might not in the short term.
