Roger G. Flittie, an inmate at the South Dakota State Penitentiary (SDSP), appeals pro se and in forma pauperis from the district court’s1 order granting appellees’ motion for summary judgment in this civil rights action. We affirm.

I. FACTS

In August of 1980, Flittie was assigned to work as an inmate law clerk in the prison library. On October 26,1981, Associate Warden Severson filed a report charging Flittie with lying or knowingly providing a false statement to a staff member — a major rule infraction. Severson’s report recommended that Flittie be relieved of his duties as library law clerk. At a subsequent hearing, the charge was downgraded from a major infraction to a minor infraction. Flittie received a reprimand, and a copy of Severson’s report was forwarded to the law library supervisor (Associate Warden Hinders). Two weeks later, Associate Warden Rist dismissed Flittie from his position as law clerk.

*278Thereafter, Flittie sought judicial review of his dismissal as law clerk pursuant to an optional review agreement stipulated to by the parties in Cody v. Hillard, 599 F.Supp. 1025 (D.S.D. 1984), aff'd, 799 F.2d 447 (8th Cir.), reh’g granted on different issue, 804 F.2d 440 (8th Cir. 1986), reh’g to 8th Cir. en banc, Jan. 12, 1987.2 No judicial review of Flittie’s dismissal has been conducted by the Cody court.

In September 1982, Flittie filed the present § 1983 complaint against Warden Solem and Associate Wardens Severson and Rist.3 Associate Warden Hinders and Officer Brown were subsequently added as defendants. Flittie alleged that he had been improperly dismissed from his position as law clerk in retaliation for exercising his constitutional rights; that Solem, Severson, and Hinders had violated his “jus tertii right” to provide legal assistance to other inmates; and that the three had unjustifiably interfered with his right of access to the courts. Flittie sought declaratory and injunctive relief as well as damages. Both sides moved for summary judgment. The district court denied Flit-tie’s motion and granted summary judgment in favor of defendants. The court stated that inmates have no constitutional right to prison jobs; that Flittie had not adequately alleged a factual basis for a retaliation claim relative to his job loss; and that the record failed to establish any unjustifiable interference with his right of access to the courts. Finally, the court stated that Flittie’s jus tertii claim would be cognizable under § 1983 only if he had also alleged that SDSP officials had failed to make other adequate legal assistance available to inmates. The court then found that the issue of the availability of adequate legal assistance had been fully and adequately litigated in Cody and thus concluded that Flittie’s jus tertii claim was moot.4 Accordingly, Flittie’s complaint was dismissed, and this appeal followed.

II. DISCUSSION

A. Summary Judgment

Flittie first argues that the district court erred in granting summary judgment because genuine issues of fact existed relative to his claims of retaliation, job loss, and not receiving a disciplinary hearing on the rule infraction written up by Assistant Warden Severson. In support of this claim, he points to factual differences in affidavits submitted by the parties.

“[T]he mere existence of some alleged factual dispute between the parties will not defect an otherwise properly supported motion for summary judgment; the requirement is that there be no genuine issue of material fact.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 106 S.Ct. 2505, 2510, 91 L.Ed.2d 202 (1986) (emphasis in original). Our review of the record reveals that the documents that were before the district court were inadequate to show the existence of a material fact question sufficient *279to preclude entry of summary judgment under the governing law.

B. Job Loss

Flittie claims that defendants dismissed him from his job as inmate law clerk in violation of his right to due process. Flittie concedes, as he must, that inmates have no constitutional right to be assigned to a particular job. See Lyon v. Farrier, 727 F.2d 766 (8th Cir. 1984); Peck v. Hoff, 660 F.2d 371 (8th Cir. 1981). He argues, however, that South Dakota inmates have a state-created substantive right to retain a job once the job is assigned, thus implicating due process procedural protections. He claims that this right has been created by various state statutes, prison regulations and a prison custom of not dismissing a prisoner from a job unless the prisoner has performed it incorrectly. We have recently held, however, that to create a liberty interest a state statute must place significant substantive restrictions on the decision making process. Dace v. Mickelson, 816 F.2d 1277, 1279-80 (8th Cir. 1987) (en banc). Additionally, the statute must contain mandatory language similar to that in the statutes in issue in Greenholtz v. Inmates of Nebraska Penal and Correctional Complex, 442 U.S. 1, 99 S.Ct. 2100, 60 L.Ed.2d 668 (1979). These “same standards apply to a review of a state rule, regulation, or practice, * * Dace v. Mickelson, 816 F.2d at 1279.

Flittie points to a statute5 that grants general powers to the warden and to a statute that prohibits corporal punishment of prisoners.6 Flittie additionally argues that two prison rules grant him a substantive right to retain his job.7 We hold, however, that these statutes and regulations do not contain language that would support Flittie’s claim. As to Flit tie’s bare allegation that it is the custom at the SDSP that no inmate can be dismissed from a job unless he commits a major rule infraction, there is nothing in the record, beyond Flittie’s assertion, of any such custom.

C. Assisting Other Inmates

Defendants told Flittie that he could not help other inmates in the law library. Flit-tie claims that this restriction violates his first amendment right to give legal assistance to other inmates. Other courts have reserved ruling on the question whether an inmate has a first amendment right to provide other inmates with legal assistance separate from the other inmates’ right to receive the legal assistance. See Kunzel*280man v. Thompson, 799 F.2d 1172, 1178 n. 6 (7th Cir. 1986); Buise v. Hudkins, 584 F.2d 223, 231 (7th Cir. 1978), cert. denied, 440 U.S. 916, 99 S.Ct. 1234, 59 L.Ed.2d 466 (1979); Bridges v. Russell, 757 F.2d 1155, 1157 (11th Cir. 1985). This court has held, however, that there is no constitutional violation in prohibiting an inmate from assisting other inmates in legal matters “so long as prison officials make available to those other inmates assistance from persons trained in the law.” Ervin v. Ciccone, 557 F.2d 1260, 1262 (8th Cir. 1977) (per curiam). The record reveals that there are currently three prison law library law clerks. Flittie asserts that he is the only inmate who can give meaningful help to the other prisoners. The district court, however, held that the issue of the South Dakota inmates’ right of access to the courts had been addressed in Cody and that therefore the issue was moot. Flittie argues that the issue is not moot because after Cody he was still prevented from assisting inmates and that thus their rights of meaningful access to the courts were violated. Flittie claims a jus tertii right to litigate this purported violation on their behalf.8 See Wilson v. State of Iowa, 636 F.2d 1166, 1167 (8th Cir. 1981) (jailhouse lawyers have standing to challenge official action that prevents them from assisting others).

We conclude that Flittie lacks the necessary standing to bring this jus tertii action. Jus tertii is based on the theory that a third party having rights is unable to claim a violation of those rights. Thus, another can gain standing to assert those rights on behalf of the third party. Rhodes v. Robinson, 612 F.2d 766, 769 (3d Cir. 1979). South Dakota prisoners asserted their rights in Cody. They still have the right to assert, if they choose to do so, a constitutional violation flowing from their being denied Flittie’s legal assistance. We conclude, therefore, that Flittie does not have a jus tertii right to assert in this case.

D. Access to the Courts

Flittie claims that his constitutional right of access to the courts was violated as a result of the restriction on his use of the law library. He was allowed to use the library only after other prisoners who were not regular users of the facility were finished with their legal work. Defendants state that this allocation system prevents domination by the regular users of the law library.

Prison inmates have a constitutional right to meaningful access to the courts. Bounds v. Smith, 430 U.S. 817, 823, 97 S.Ct. 1491, 1495-96, 52 L.Ed.2d 72 (1977). Access to the law library may be restricted, however, as long as the restrictions are reasonable. See Johnson v. Avery, 393 U.S. 483, 490, 89 S.Ct. 747, 751, 21 L.Ed.2d 718 (1969). After the restrictions were imposed, Flittie used the prison law library on the average of three days a week. We hold that this is a reasonable restriction imposed for a rational reason.

Additionally, Flittie has not shown any prejudice resulting from these restrictions. As the district court pointed out, Flittie has filed six other actions since the present case was filed in September of 1982. See Grady v. Wilken, 735 F.2d 303 (8th Cir. 1984) (per curiam) (non-prejudicial effect of alleged constitutional violation was factor in affirming district court). Thus Flittie has not established a denial of his first amendment right of access to the courts.9

E. Disciplinary Hearing

Flittie asserts that he was not given a disciplinary hearing regarding his alleged rule infraction as mandated by Wolff v. McDonnell, 418 U.S. 539, 94 S.Ct. 2963, 41 L.Ed.2d 935 (1974). He alternatively claims, however, that he was fired as prison law clerk as a direct result of a disciplinary hearing. The record reveals that he did receive some type of hearing. As earli*281er stated, however, Flittie had no substantive liberty interest in retaining his job as prison law clerk and thus had no right to procedural due process protection. In any event, Flittie has failed to show a direct link between the hearing and his dismissal as prison law clerk. The copy of the rule infraction report was sent to his prison law library supervisor (Hinders) by the three-member disciplinary board.10 It was Warden Rist, however, who dismissed Flittie as law clerk.

Flittie additionally claims he was denied equal protection in that he was given a hearing on his rule infraction different from that which other inmates would have been given. To prove an equal protection claim, Flittie must show treatment that was invidiously dissimilar from that accorded other inmates, with no rational basis existing for the difference in treatment. Burns v. Swenson, 430 F.2d 771, 778 (8th Cir. 1970), cert. denied, 404 U.S. 1062, 92 S.Ct. 743, 30 L.Ed.2d 751 (1972). The record reveals little information on what actually happened regarding the hearing. Taking into account the meager facts that were before the district court, it appears that Flittie received the type of hearing that all prisoners charged with a minor rule infraction would have received, and thus no equal protection violation has been established.

F. Retaliation Claim

Finally, Flittie alleges that defendants took the above-discussed actions in retaliation for his legal activities. The district court concluded that the allegations in Flit-tie’s pleadings and other documents he submitted in connection with his motion for summary judgment provided an inadequate factual basis for a retaliation claim.

Prison officials may not retaliate against an inmate for exercising constitutional rights. However, as discussed above, Flittie had no constitutionally protected right in retaining his job, providing legal assistance to other inmates, or in receiving a Wolff v. McDonnell type hearing. With respect to Flittie’s allegations that defendants retaliated against him for exercising his own right of access to the courts, the record supports the district court’s conclusion that Flittie’s allegations are simply too broad and conclusory to support a claim for § 1983 relief. See Ervin v. Ciccone, 557 at 1262 (broad allegations of retaliation are not sufficient to support a claim for violation of constitutional rights).

III. CONCLUSION

The district court’s order is affirmed.
