Ask for help for the meaning of a sentence in a passage.

We visited the corporate headquarters of Best Buy, the electronics retailer, in Richfield, Minn. Employees Stacy Verstraight, Jason Dehne and Marissa Plume say that putting in 60- to 80-hour weeks got them pats on the back.

"You know, you'd send an e-mail at nine o'clock at night. And the next day your co-workers would say, 'Hey, wow, you were up really late last night. What were you doing, you are working the whole time? Wow. Great job,'" says Marissa.

But if you weren’t there at the crack of dawn, you were put down.

"You know, if I come in at nine o'clock or 10 o'clock, I was at a doctor's appointment, you know, people are saying, 'Oh gee. Glad you could show up today.' You know, so it felt a little bit of a dig," says Stacy. "And people were just watching other people. So it felt like a lot of unnecessary pressure."


Above is the scripts of a program, yesterday I asked the meaning of the phrase "put donw"in this forum, but I'm still a little bit confused about the sentences.But if you weren’t there at the crack of dawn, you were put down. What is "there", Does "there" means office, and I know "at the crack of dawn" is the very early moning. Does this whole sentence means " If you can't gut up very early and go to work and appears in office , your college in office will laugh at you because although you worked very late last night but you can't get up early the next moring and go to work on time, so the college in the office will laugh at you( so you were put dawn)

Is my understanding correct?

Thanks for you help.
