Task: songer_casetyp1_6-3

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "labor relations". 

PER CURIAM ORDER.
The National Labor Relations Board seeks enforcement of its orders issued against the respondent, Davis Transport, Inc. The Board’s Decision and Order issued on January 31, 1968, is reported at 169 N.L.R.B. No. 80 and its Supplemental Decision and Order issued on January 27, 1970, is reported at 180 N.L.R.B. No. 148. The Board found violations of Section 8(a) (1) of the Act due to the respondent threatening its employees with reprisals, soliciting their withdrawal from the union and promising benefits for withdrawal. It was also found that Section 8(a) (3) and (1) were violated because certain employees were discharged by the respondent because of their union membership.
In this Court the respondent has abandoned its opposition to most of the Board’s findings of unfair labor practices and now contends only that the Board erroneously found that the respondent violated Section 8(a) (5) and (1) of the Act by refusing to bargain with the union. The crucial issue is whether the Board abused its discretion in determining what employees constituted an appropriate bargaining unit. We conclude that the Board has articulated substantial reasons for its determination of the appropriate bargaining unit which are supported by substantial evidence on the record as a whole.
Therefore, it is ordered that the orders of the Board be enforced.
