1. Summarize the facts and procedural background of the case.
2. Under the Spielberg-Olin policy of deferral to existing arbitration awards, was the ALJ obligated to defer to the arbitrator’s decision that Bedell had assaulted his supervisor and was discharged for just cause?
3. Can additional facts change the credibility determinations of witnesses?

[The NLRB petitioned the court to enforce its order finding that Yellow Freight had violated Sections 8(a)(1) and 8(a)(3) of the NLRA. The company contended that the Board's order should not be enforced because it failed to defer to specific facts found by an arbitrator that Lonnie Bedell assaulted a supervisor.]

Facts and Procedural History
Lonnie Bedell was hired in 1983 as a dock worker at Yellow Freight's Carlstadt, New Jersey, facilities. His testimony as to the relevant facts set forth below was credited by the ALJ following a hearing. In April 1986, Bedell observed JoAnne DeGrosa, the sales secretary, crying in the company parking lot after she had dropped her keys. DeGrosa told Bedell that she had been sexually harassed by branch manager Dan Hamlin and sales manager Kenny Dore. Bedell reported the incident to his shop steward the following evening and requested that the steward discuss the allegations with Dore. Dore approached Bedell a day later, and told him that DeGrosa was not a union member and that the matter was none of Bedell's business.
The sexual harassment continued, and DeGrosa was discharged three months later. Bedell accompanied DeGrosa to the New Jersey Division of Civil Rights, assisted her in filing a claim with the Equal Employment Opportunity Commission, and signed an affidavit on her behalf. Thereafter, Bedell posted on the union's bulletin board a newspaper advertisement for an upcoming television series on workplace sexual harassment. As he did so, Bedell commented to a supervisor that Dore and Hamlin "shouldn't have done that to JoAnne DeGrosa."

Shortly after these events occurred Bedell's supervisors began to give him more arduous and dangerous assignments, such as transporting heavier loads without mechanical assistance and working in the hazardous area of the dock where corrosive liquids are stored, even though he was the most senior dock worker at the Carlstadt facility. Bedell also was subjected to frequent workplace harassment. Although he apparently complained on several occasions to his supervisors and to the union officials, Bedell continued to be harassed. Bedell left the Carlstadt facility in 1987 and transferred to Yellow Freight's new terminal in Elizabeth, New Jersey. Dore was then appointed as the operations manager in Elizabeth. Bedell was again assigned harder and more demeaning work than he had been assigned before he assisted JoAnne DeGrosa, such as cleaning the coffee room and working without the use of the forklift truck and drag line.
Bedell filed his own charge with the Equal Employment Opportunity Commission on January 19, 1988, in which he asserted that he was being subjected to constant harassment in retaliation for the assistance he rendered to DeGrosa in opposing Dore's and Hamlin's sexual harassment practices. On February 3, 1988, Bedell was assigned to unload and move 40 cartons, each weighing 24 pounds. While he was in the process of placing them into three carts, his supervisor Joseph Smidt ordered him to consolidate the cartons into two carts.
Bedell and Yellow Freight contest the events that followed this order. Bedell contends that he told Smidt that he would follow the order but added
"and I am not a piece of shit," in protest of the continuous harassment. Yellow Freight claims that he refused to follow the order, exclaiming "because you're a big piece of shit…. [a]nd you're a scum bag, too." Smidt testified that Bedell came toward him waving his hands up and down and staring with a crazed look in his eyes. Smidt is 6 feet 2 inches tall, weighs 260 pounds, is 20 years younger than Bedell, and is a judo and karate champion. Bedell weighs 170 pounds. Smidt testified that he nevertheless feared bodily injury because he had heard rumors that Bedell carried a gun and had used it to threaten others. Smidt testified he turned and walked quickly to Dore's office. Bedell testified Smidt walked away and talked to the shift operation manager who was 30 or 40 feet away, and who told Bedell to go to Dore's office.
Bedell was thereafter discharged for disobeying a direct order and assaulting a supervisor. Bedell filed a second complaint with the Equal Employment Opportunity Commission, alleging that he was fired in retaliation for filing his first EEOC complaint.
Bedell also filed a grievance based on his discharge which was arbitrated at a two-day hearing. Bedell retained personal counsel to represent him who also represented the union, Local 641 of the International Brotherhood of Teamsters, Chauffers, Warehousemen and Helpers of America, AFL-CIO. Bedell was permitted to call his own witnesses and to crossexamine Yellow Freight's witnesses.
The hearing was limited, without objection by Yellow Freight, to the issue of whether there was just cause for Bedell's termination under the collective bargaining agreement entered into between Yellow Freight and the union. Bedell's lawyer stated on the record that he did not intend to raise any of the issues pertaining to Bedell's EEOC charges. The arbitrator found that although Bedell did not disobey a direct order, he did assault his supervisor, and there was therefore just cause for his discharge. He noted in his opinion that, "[t]he grievant's credibility was substantially diminished by the fact that he did not previously grieve what he characterized as unfair treatment when he was ordered to push his carts and not to use the drag line." Bedell appealed the arbitrator's decision to the Superior Court of New Jersey, which affirmed without opinion.
Finally, Bedell filed charges with the National Labor Relations Board alleging that his discharge by Yellow Freight constituted an unfair labor practice.
The administrative law judge conducted a hearing after the arbitrator's decision was made. The ALJ found that Yellow Freight committed unfair labor practices in violation of sections 8(a)(1) and 8(a)(3) of the NLRA because Bedell was harassed and discharged for supporting DeGrosa's sexual harassment claim. In so finding, the administrative law judge concluded that much of the testimony supporting Yellow Freight's allegations that Bedell committed an assault was not credible. The ALJ refused to defer to the arbitrator's finding that Bedell had assaulted his supervisor, noting, "[i]t would not be appropriate to do so as the conflicting accounts presented to me for resolution are necessarily enmeshed with the evidence bearing on the EEOC matters."

The Board affirmed the ALJ's rulings, findings, and conclusions. It adopted the recommended order which directed Yellow Freight to (1) cease and desist from discriminating against and coercing employees in the exercise of their rights guaranteed by the NLRA; and (2) reinstate Bedell with back pay and full seniority and remove from his files any reference to his unlawful discharge.…
