Panel 1: Ooh, here we go. Although it appears that Mike didn't know about the meeting until just now. His desk has an odd perspective; the only time I saw a desk with a slant to it like that, I was baked out of my mind. And his name and position seem to be painted right on his door, rather than embossed on a nameplate. And why "Mike" Patterson, rather than "Michael"? Full names are generally more professional and authoritative.
Panel 2: Mike's getting the ax.
Panel 3: "Gluttson"? Oh, that's beyond Dickensian.
Panel 4: Okay, not quite. Mr. Integrity, who looks as if he's been asked to physically execute people, will react as if deciding who gets fired is Sophie's choice, and tell his boss, "I fire...me." After all, Mr. Gluttson has teeth, so we know he's evil.
