Translation:You are sick, do not go to work tomorrow.
I noticed that too; we should definitely report it. But just in case you don't already know and are wondering, the character 假 is one of the few Chinese characters that has two pronunciations. When it means "fake" or "suppose", it takes on the 3rd tone; when it means "holiday", it is in the 4th tone.
That said, you're right that the audio doesn't match the pinyin, even though it actually does match the character.
