I've worked corporate jobs all my life, and I was never one misunderstood message away from being fired. Instead they would've talked to me and, even if they figured it was my fault, they would've given me a warning since it was the first time. No worthwhile employer is firing people for the first offense, corporate or otherwise.

100% you have been, you just didn't understand nor send the wrong message.
As a sidenote, working for a Corporation is not solely the bar for what people mean when they say working for Corporate. "Corporate" implies a larger organization that promotes policies developed under different circumstances to your work environment which minimizes liability and promotes homogeneity in all aspects of the working experience.
