In the US, contracts like this aren't really a thing for tech employees.
You are an at-will employee, offer can be rescinded or reneged at any time for any reason unless it is specifically a prohibited reason.

Why do you think businesses tend to be benefit the most? There are historically twice as many quits as separations, so workers are twice as likely to use "at will employment" to leave then having the Business use it to fire them. I can't think of any data to support the notion that the bulk of the benefits are not borne by workers, but if you have some, I'd be interested in hearing it.
