The sooner you start, the sooner the clock begins. Anything the company does to try to blackball you will be held against them in the adjudication process. If you file a private discrimination claim in Superior Court, you will be asked to go through a legal process of dropping your government complaint. However, that’s a long way off to make that type of decision.
I see at least 4 labor law violations in just what you have written. In addition it is inexcusable to pay a B2B (I’m assuming — you were selling the Yelp ads to small businesses, right) sales person as this is, especially for such a large, profitable high profile company.
Yelp is without question subject to the FMLA (Family Medical Leave Act) and here is the applicable California law.
As I said, I didn’t care for Yelp’s horrible “Elite” Yelp program where GenXers take dumps all over hardworking businesses, especially in the restaurant industry — one of the hardest industries of all. I didn’t care for what happened with Talia Jane even though Todd Hannula made it clear there was something more in the works than just her letter. Even in her letter, it was obvious there was an exploitive situation with employees — like giving discounted snacks and food on the job instead of — like — pay. All that is crap shitty employers do to get around on their bottom line. Another concern she mentioned that was a big red flag to me was the “You have to work in customer service for a year before you can move to a higher job.” And she said she was hired immediately, at her first interview? Those are all red flags that the company is just trying to get as close to free work as it can.
Which even for a small business, is bad. For a big business it sucks and they are subject to all provisions of California’s labor and anti-discrimination laws as well as Federal Laws. Do it. There are labor lawyers who would LOVE to take this on I am certain.
