"...in recent years in Silicon Valley there has been an enormous increase in the use of arbitration clauses in employee contracts—a legal strategy pioneered by Wall Street firms..."

The paragraph I lifted the above quote from follows and you can read Sheelah Kolhatkar's entire piece here.

"Meanwhile, the tech industry continues to erect barriers to legal action. A recent study by the law firm Carlton Fields Jorden Burt found that in recent years in Silicon Valley there has been an enormous increase in the use of arbitration clauses in employee contracts—a legal strategy pioneered by Wall Street firms, whereby disputes such as harassment must be settled through arbitration rather than litigated in federal court. The arbitration process is both shielded from public scrutiny and generally considered more favorable to employers. Tech companies have also embraced the use of employee confidentiality and nondisclosure agreements. Ostensibly, such agreements exist to protect company secrets, but when they are too broad they prevent employees from comparing salaries or talking publicly about their experiences at work. One former Google employee told me, "I wish we could have a twenty-four-hour moratorium on N.D.A.s, because that day would rock the tech industry."
