Mmmm if you don’t work and make money in the US you’ll be in a bad way, and since the majority of employers have the conditions described, and most job seekers have little negotiating leverage on these issues, the choice to sign the employment contract is voluntary, yes, but so much behind the circumstances and conditions of that signing is beyond the power of an individual to effect or influence through their choices. Which is why the saying “strength in numbers” is a saying.
