IANAL, but all I know of the National Labor Relations Act pertains to unions and collective bargaining. These were UX designers, far detached from warehouses, speaking on warehouse conditions. While warehouse workers could file suit under the National Labor Relations Act if fired for speaking publicly of their own working conditions, I'm not sure that Amazon's UX team would qualify (but again, IANAL). To draw an analogy: Would a DoorDash engineer be safe speaking out against the working conditions of DoorDash drivers?
