This сonsolidated appeal is before the Court on petition of the National Labor Relations Board to enforce the Board’s orders finding that the Leatherwood and Brahaney Drilling Companies each violated §§ 8(a)(5) and (1) of the National Labor Relations Act, 29 U.S.C. §§ 158(a)(5) and (1), by withdrawing recognition from and refusing to bargain with Lоcal 826, International Union of Operating Engineers, AFL-CIO (the Union). Both drilling companies challenge the sufficiency of the evidence to support the Board’s conclusion that neither could assert good faith doubt of the Union’s majority status as a justification for refusal to bargain. We enforce the Board’s orders.
Leatherwоod and Brahaney are two of the fifty to sixty oil well drilling companies who operate in the Permian Basin, an area of 95,000 square miles in Western Texas and Eastern Nеw Mexico. Companies in this area normally take
*272
less than twenty days to drill a well, then move the rig to a new site where a substantially new crew may be hired or the old crew rehired, resulting in high employee turnover. Taking this employment pattern into account, the Board fashioned and we approved a special voter-eligibility formula

for elections to certify the employee bargaining representatives in this particular area. Hondo Drilling Co.,
It is settled that in the absence of special circumstances, a union’s majority status, once established by a valid election, is irrebuttably presumed for а reasonable period, ordinarily one year, following the Board’s certification of the union. Brooks v. N.L.R.B.,
At the administrative hearing, the companies argued that the facts support doubt of the Union’s majority status, based upon (1) the employee turnover rate; (2) the five to ten month Union silence immediately preceding withdrawal of rеcognition; and (3) in the case of Brahaney, evidence of employee indifference to the Union.
The Administrative Judge who presided over both cases fоund the following *273 facts. The Union had not communicated with either Brahaney or Leatherwood for five to ten months immediately preceding withdrawal of recognition, but this silence, together with other delays in the two-year history of the bargaining, was caused by the Union’s low manpower, the geographic dispersal of all the Basin drilling сompanies, and the Union’s belief that Leatherwood and Braha-ney had reduced operating levels. Although employee turnover had reached 900% during the last period of Union silence and Brahaney and Leatherwood each employed less than four of the original certification voters out of the prеsent work force of eligible voters numbering as high as seventy-seven, such turnover was not uncommon among Basin companies and had been assumed to be inherent in thе industry under the Hondo formula. Harman, the attorney for both Leatherwood and Brahaney, was “highly familiar with the history of organization by this Union in the Permian Basin,” and, as attorney fоr other Basin drilling companies, had met with a Union representative on numerous occasions during the period of Union silence toward Leatherwood and Brahaney. The sole evidence of employee indifference was testimony by a Brahaney manager that he did not hear employees speak of the Union.
The Administrative Judge concluded that (1) even 900% employee turnover did not support doubt of majority, in view of Hondo’s recognition of inherent turnover in this industry; (2) occasional Union silences were known by the companies to be the result of the Union’s low manpower and not any erosion of Union support; and (3) there is no substantiаl evidence of employee indifference to the Union. Accordingly, he found that none of the claimed grounds supported a reasonable doubt of mаjority and recommended that the two companies be ordered to bargain with the Union representatives and to desist from unfair labor practices. The Board adopted these findings as well as the proposed order.
The appellants do not dispute the factual data in the Board’s order; but they cite other facts on the record to argue that other inferences should have been drawn or that, at the least, the burden of proof was necessarily shifted to the Uniоn and not met by it. They emphasize the magnitude of 900% employee turnover. But in our view, this only reargues what has been decided in Hon-do, i. e., that turnover is inherent in this industry and cannоt be given independent significance as a sign of Union weakness. N.L.R.B. v. Hondo Drilling Co., supra at 944—946.
Disputing that the Union’s low manpower and the companies’ dispersal were the evident causes of the Union silence, appellants point out that other union assistants were available to the two Union negotiators and that the Uniоn’s negotiations followed the same pattern in the case of at least five Basin companies. Nevertheless, we agree with the Board that such a negоtiating team, faced with over fifty companies in a 95,000 square mile area, would necessarily fail to communicate with one or more companies at intervals without raising doubt of its majority status.
Finally, appellants challenge the basis for distinguishing other Board cases in which the Board found that the facts supported reasоnable and good faith doubt of majority status. See Taft Broadcasting, WDAF—TV,
On the record as a whole and given the province of the Board, we agree that the appellants have not overcome the presumption of continuity of majori *274 ty status and, therefore, have no room for good faith doubt of the viability of the Union’s continued representation of the bargaining unit.
Enforced.
