If you mean the 1985 scabs then
"Supplementary Base Vacancy Bid 1985-5" (85-5 bid) that it would fill a large number of anticipated vacancies using a system that allows pilots to bid for positions and that, in the past, had assigned positions by seniority. Although ALPA authorized strikers to submit bids, Continental announced that all of the positions had been awarded to working pilots. ALPA and Continental then agreed to end the strike, dispose of some related litigation, and reallocate the positions covered by the 85-5 bid. Striking pilots were offered the option of settling all outstanding claims with Continental and participating in the 85-5 bid positions' allocations, electing not to return to work and receiving severance pay, or retaining their individual claims against Continental and becoming eligible to return to work only after all the settling pilots had been reinstated. Thus, striking pilots received some of the positions previously awarded to the working pilots. After the settlement, respondents, former striking pilots, filed suit in the District Court against ALPA, charging, inter alia, that the union had breached its duty of fair representation. The court granted ALPA's motion for summary judgment, but the Court of Appeals reversed. It rejected ALPA's argument that a union cannot breach the fair representation duty without intentional misconduct, applying, instead, the rule announced in Vaca v. Sipes, 386 U.S. 171, 87 S.Ct. 903, 17 L.Ed.2d 842 that a union violates the duty if its actions are "arbitrary, discriminatory, or in bad faith," id., at 190, 87 S.Ct., at 916. With respect to the test's first component, the court found that a nonarbitrary decision must be (1) based upon relevant permissible union factors, (2) a rational result of the consideration of those factors, and (3) inclusive of a fair and impartial consideration of all employees' interests. Applying that test, the court concluded that a jury could find that ALPA acted arbitrarily by negotiating a settlement less favorable than the consequences of a complete surrender to Continental, which the court believed would have left intact the striking pilots' seniority rights with regard to the 85-5 bid positions. It also found the existence of a material issue of fact whether the favored treatment of working pilots in the allocation of the 85-5 bid positions constituted discrimination against the strikers.
If you meant to type 57 or 570 THEN
570 – A group of pilots hired in 1985 as United was trying to break the union. They all agreed to scab (in writing) and were trained and sent home. Their job was to cross the picket line when the strike was called. ALPA got a hold of them, and most did not cross (although they emboldened the CEO and gave him what he thought was a tool to win the strike). Since they needed a lot of people (and fast), they ended up with some nut jobs. (Many pilots of the era who wanted to work for UAL stayed away, not wanting to be scabs). Most of these pilots were young, and entered a very mature work force. They upgraded quickly, and many will have over 25 years as heavy Captains. They have had the best careers of any United pilot since the 1960’s (late 60’s and 70’s era pilots furloughed, 20 year Captain upgrade, etc.), but these pilots will whine all day long about how bad they have it (even in the presence of double furloughees). They see themselves heroes of a strike that they helped cause, and are generally disliked among other United pilots (this may be a surprise to them but, whenever the number 570 comes up in the cockpit, you can expect a long list of complaints against them). Like any group, there are some really good guys and gals that are 570’s. They’re not all bad.
