1633, 1647, 40 L.Ed.2d 15 (1974), when it was challenged as overly broad and violative of the first amendment. To require simply that an organization, to qualify for checkoff benefits, must have as “one of its objectives” promoting an efficient and effective work force, and that any affiliated employee association have a similar objective, would not violate fourteenth amendment standards in our view. This does not constitute content or subject matter speech prohibition nor denial of a forum as proscribed in a picketing ordinance context in Police Dep’t v. Mosley, 408 U.S. 92, 92 S.Ct. 2286, 33 L.Ed.2d 212 (1972), or Carey v. Brown, 447 U.S. 455, 100 S.Ct. 2286, 65 L.Ed.2d 263 (1980), as contended by plaintiffs. After careful scrutiny of the statute, we find there to be a rational basis bearing a relationship to legitimate state purposes for subsection 5, and that subsection 5 is not violative of plaintiffs’ constitutional rights. The preamble to the Union’s constitution emphasizes exercise of both rights and responsibilities of citizenship; it is not clear that the locals may not themselves meet the subsection 5 requirements despite the letter of potential disqualification noted by the trial judge. 516 F.Supp. at 616. This subsection (5) standard, applicable to whether a public employer would allow a checkoff or not, involves only a standard of reasonableness and reasonable is evaluated “with ‘some basis in practical experience.’ ” City of Charlotte v. Local 660, 426 U.S. 283, 287, 96 S.Ct. 2036, 2039, 48 L.Ed.2d 636 (1976) (quoting South Carolina v. Katzenbach, 383 U.S. 301, 331, 86 S.Ct. 803, 820, 15 L.Ed.2d 769 (1966)).
In a related aspect of this standard, it has been held that to undermine, rather than to “promote, the effective performance” of a public official’s job was an important determination in deciding constitutionality of a political discharge. See Branti v. Finkel, 445 U.S. 507, 518-19, 100 S.Ct. 1287, 1294-95, 63 L.Ed.2d 574 (1980). We find that the statute requiring promotion of an efficient and effective work force in order for labor associations to qualify for dues checkoff is not unconstitutional.
Unlike other provisions of the Constitution, the Equal Protection Clause confers no substantive rights and creates no substantive liberties. The function of the Equal Protection Clause, rather, is simply to measure the validity of classifications created by state laws.
San Antonio Independent School District v. Rodriguez, 411 U.S. 1, 59, 93 S.Ct. 1278, 1310, 36 L.Ed.2d 16 (1973) (Stewart, J., Concurring). Further, we find that the statutory language used in this subsection is not so vague and indefinite that it should be construed to be unconstitutional on equal protection grounds.
3. Subsection 6 (Independent Employee Organization):
This subsection deals with and proscribes a labor organization’s affiliation with another such organization if it is to be given checkoff benefits. The issue here is whether this requirement must be analyzed under the rational basis standard, or whether strict scrutiny must be applied.
An “affiliate” in an organization is defined for some purposes as an associate. To be affiliated with a group or organization is to be associated with, attached to, or identified with that organization. We believe this subsection directly limits freedom of association between labor organizations, and their members or members of other such organizations, and thus it could restrain or restrict freedom of association, a fundamental first amendment right. The advocacy of particular policies and practices of parent or affiliated organizations may well be directly affected by this limitation, and thus it requires strict scrutiny; equal protection concerns in this respect are related to the first amendment rights asserted by plaintiffs. See NAACP v. Alabama ex rel. Patterson, 357 U.S. 449, 460, 78 S.Ct. 1163, 1170, 2 L.Ed.2d 1488 (1958); Gibson v. Florida Legislative Investigation Comm., 372 U.S. 539, 549, 83 S.Ct. 889, 895, 9 L.Ed.2d 929 (1963).
We have considered in this same context the conditions set out in subsections (4) and (5) and have found no explicit prohibition or discrimination which has directly and adversely impacted upon freedom of speech,
