I can understand your work 'episode'.
An employee of mine was doing her work, answering emails and helping clients and then the CEO came into the office (manager notified him) and accused her of not responding to a clients email for a week. That's not excusable, I understand that she was doing her work and not playing around yet on the other hand managers can be uptight and nervous about unrelated issues and they let it out on employees. No excuse but it's the way most work forces operate.

Hope you have a better day tomorrow and you get some slack.
