The next step in this case is for a 3-member panel of the NLRB (a 5 member board appointed by the President, currently with 4 members) to decide whether to accept the proposed ruling of the ALJ or to substitute their own opinion of how the case should come out.
Orders of the NLRB are not self-executing, so parties can appeal an adverse judgement to the Circuit of Appeals of their choice and the NLRB can cross-petition for enforcement of their decision. The Federal courts have final say over questions of law like “are non competes a violation of labor law”.
The entire process takes several years to play out.
