OPINION
¶ 1 Appellants Rudy and Alice Gamez challenge the trial court’s grant of summary judgment in favor of appellee Brush Well-man, Inc., Rudy’s former employer. The Gamezes argue that the trial court erred in rejecting their claims for wilful misconduct, breach of contract, and bad faith stemming from Rudy’s employment-related exposure to beryllium. They also challenge the trial court’s award of sanctions against them for refusing to accept an offer of judgment. We affirm the trial court’s grant of summary judgment in favor of Brush Wellman, but vacate the court’s award of sanctions against the Gamezes.
¶ 2 When reviewing the grant of a motion for summary judgment, we view the facts in the light most favorable to the nonmoving party.
Southwest Auto Painting & Body Repair, Inc. v. Binsfeld,
¶ 3 The Gamezes sued Brush Wellman in June 1996 for wilful misconduct, contending that Brush Wellman had “engaged in [a] course of conduct knowing that such conduct was likely to cause extreme physical, financial and emotional hardship to Plaintiffs.” They later amended their complaint to add claims for breach of contract and bad faith. The trial court granted summary judgment on all three claims and awarded costs in the *269 amount of $65,121.58 to Brush Wellman as a sanction pursuant to Rule 68, Ariz. R. Civ. P., 16 A.R.S., Pt. 2.
¶ 4 Summary judgment should be granted if “there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law.” Ariz. R. Civ. P. 56(c), 16 A. R.S., Pt. 2;
Sanchez v. City of Tucson,
¶ 5 The Gamezes first contend that Rudy’s injury resulted from Brush Wellman’s wilful misconduct and, thus, that the trial court erred in granting summary judgment in favor of Brush Wellman on this claim. It is well settled that work-related injury claims are generally redressed exclusively under Arizona’s workers’ compensation scheme. A.R.S. § 23-1022. Thus, such claims are controlled by A.R.S. § 23-1024(A), which provides that “[a]n employee ... who accepts [workers’] compensation waives the right to exercise any option to institute proceedings in court against his employer.”
See Anderson v. Industrial Comm’n,
¶ 6 The question, then, is whether a material issue of fact exists that Brush Well-man engaged in wilful misconduct so as to allow the Gamezes to overcome the presumption of waiver in § 23-1024(A). A wilful misconduct action includes four elements: (1) the employer’s wilful misconduct must have been the cause of the employee’s injury, (2) the wilful misconduct must have been “an act done ... knowingly and purposely with the direct object of injuring another,” (3) the act that caused the injury must have been the personal act of the employer, and (4) the act must have reflected “a wilful disregard of the life, limb or bodily safety of employees.” Ariz. Const, art. XVIII, § 8;
see Serna v. Statewide Contractors, Inc.,
¶ 7 Gross negligence is not sufficient to establish wilful misconduct under § 23-1022.
Serna.
The “direct object” of the employer’s actions must have been to “injurfe] another.” § 23-1022(B);
see Allen v. Southwest Salt Co.,
cannot ... be stretched to include accidental injuries caused by the gross, wanton, wilful, deliberate, intentional, reckless, culpable, or malicious negligence, breach of statute, "or other misconduct of the employer short of a conscious and deliberate intent directed to the purpose of inflicting an injury.
Even if the alleged conduct goes beyond aggravated negligence, and includes such elements as knowingly permitting a hazardous work condition to exist, knowingly ordering employees to perform an extremely dangerous job, wilfully failing to furnish a safe place to work, wilfully violating a safety statute, ... or withholding information about worksite hazards, the conduct still falls short of the kind of actual intention to injure that robs the injury of accidental character.

*270 ¶8 In Sema, two employees were killed after a ditch collapsed. The workers’ families sued the employer for wrongful death, alleging that the deaths were the result of the employer’s wilful misconduct under § 23-1022 and, therefore, that workers’ compensation was not the exclusive remedy for their claims. The trial court granted summary judgment in favor of the employer, and Division One of this court affirmed, even though the facts showed that the ditch was twenty-five feet deep and insufficiently sloped or shored to prevent a cave-in. Indeed, a previous cave-in had buried one of the decedents to his waist. And, there was no safety ladder near the men at the place in the ditch where they had been digging. Moreover, before the accident, state industrial commission inspectors had warned the employer of the very conditions that caused the deaths and had recommended corrective measures. And although Division One stated that it had “no difficulty in finding that the cave-in causing the deaths of the decedents was the direct result of the refusal to follow the safety recommendations of the Commission’s inspectors,” the court concluded:
It would appear that our statute as well as the principles governing the interpretation of the workmen’s compensation statutes which provide for suit at common law for the employer’s willful misconduct require that there be deliberate intention as distinguished from some kind of intention presumed from gross negligence. 2 Larson, Workmen’s Compensation Law, See. 69.20 (1961). The Arizona statute is most restrictive in this regard. It is the opinion of this Court that the facts presented on review, viewed in the light most favorable to the plaintiff-employees, clearly establish the negligence of the defendant-employer but fail to establish that the employer, through its elected officer, acted with the intent required by our statute. A.R.S. § 23-1022____We must regretfully state that under our statutes the facts do not bring appellants within the exception of A.R.S. § 23-1022.
Serna,
¶ 9 Our courts have reached similar conclusions in
Diaz v. Magma Copper Co.,
¶ 10 Even viewed in the light most favorable to the Gamezes, the evidence they presented does not show that Brush Wellman acted knowingly or maliciously or that it disregarded the dangers its employees face when working with beryllium; that Brush Wellman intentionally failed to warn its employees of what the Gamezes claim is a substantial certainty that they will develop CBD; or that Brush Wellman sacrificed employee safety for higher profits. Instead, the evidence shows that Brush Wellman informed Rudy of the risks involved in working with beryllium during his first interview for prospective employment. But, even if all of the Gamezes’ allegations had been proved, they would not establish that Brush Wellman’s direct objective was to cause injury to Rudy
*271
because, in this state, there must be a “ ‘genuine intentional injury,’ comparable to ‘an intentional left jab to the chin.’ ”
Allen,
¶ 11 Because the Gamezes failed to show that Brush Wellman intended to cause injury to Rudy, we agree with the trial court’s conclusion that their claim does not fall within the wilful misconduct exception of § 23-1022(A). Therefore, the trial court properly entered summary judgment against the Gamezes on this claim.
¶ 12 We also conclude that the trial court correctly granted summary judgment on the Gamezes’ breach of contract and bad faith claims. On the breach of contract claim, the trial court ruled:
At the time of [Rudy’s] hire, [Brash Well-man] ha[d] a 1989 policy in effect that provided for certain benefits if an employee was diagnosed with berylliosis. On January 1, 1992, [Brash Wellman] had in effect an ERISA [Employee Retirement Income Security Act] plan that provided for certain benefits in the event that one of its employees contracted [CBD]. In 1992, [Rudy] was told of the adoption of the new plan and that it applied to him. In 1993, testing on [Rudy] demonstrated he was sensitized to beryllium, but had no evidence of beryllium disease. In 1995, [Rudy] was first diagnosed with CBD.
... The 1992 ERISA plan governs [the Gamezes’] claim as the 1989 plan only applied to persons diagnosed with berylliosis. [Rudy] was first diagnosed with CBD in 1995 and 1993 testing demonstrated no beryllium disease. [Brash Wellman] validly modified its disability benefits plan with respect to beryllium disease, effective January 1, 1992. As of January 1, 1992, [Rudy] had no vested rights in the 1989 plan, as the triggering of benefits under that plan only occurred upon the diagnosis of berylliosis.
¶ 13 In addition to its 1989 policy, on which the Gamezes do not rely and which Rudy never saw, Brash Wellman had orally represented to Rudy when he was hired in 1991 that, if he ever developed CBD, he could leave his job but continue to receive his full wages and benefits for life. The Gamezes maintain that, because Rudy never received consideration for or accepted Brash Well-man’s offer to modify the “full wages and benefits for life” term of Rudy’s original employment contract, the 1992 ERISA plan neither applied nor was effective as to him, and therefore, they are not precluded under 29 U.S.C. § 1144(a) from suing for breach of contract. Section 1144(a) preempts all state laws that relate to any employee benefit plan established or maintained by an employer to provide benefits in the event of “sickness, accident, disability, death or unemployment.” 29 U.S.C. § 1002(1)(A). Because the Gamezes’ claim, based on Rudy’s alleged oral contract with Brush Wellman at the time he was hired in 1991, relates to the same matter as the ERISA benefits policy, their common law breach of contract claim is preempted.
See Shaw v. Delta Air Lines, Inc.,
¶ 14 We also note that the case of
Bartholet v. Reishauer A.G. (Zurich),
¶ 15 Essentially, the Gamezes challenge the trial court’s grant of summary judgment on their breach of contract claim on the ground that the “record contains no evidence of a valid unilateral modification of the parties’ 1991 [oral] contract.” In support of their claim, the Gamezes argue that, “[i]n
Demasse v. ITT [Corp.],
[
¶ 16 Although our supreme court held in Demasse that “[a]n employer cannot unilaterally modify and thus negate the effect of implied-in-fact contractual terms,” it did so because “the question certified [from the Ninth Circuit Court of Appeals] positfed] that the Demasse employees have a contract term providing them layoff seniority rights.” Id. at ¶ 51. Moreover, Demasse was an employment security case based on the employee handbook, not an employment benefits case. 1 And, in reaching its ultimate holding, the court explained that:
At-will employment contracts are unilateral and typically start with an employer’s offer of a wage in exchange for work performed; subsequent performance by the employee provides consideration to create the contract. Thus, before performance is rendered, the offer can be modified by the employer’s unilateral withdrawal of the old offer and the substitution of a new one: the employer makes a new offer with different terms and the employee again accepts the new offer by performance (such as continued employment). Thus a new unilateral contract is formed — a day’s work for a day’s wages.
Id. at ¶ 12 (citations omitted).
¶ 17 Moreover, Rudy’s diagnosis of CBD followed Brush Wellman’s adoption of its CBD benefits .policy on January 1, 1992. Brush Wellman could modify the benefits package it had offered Rudy when he was hired because his right to those benefits had not vested because he did not contract CBD during the applicable period, i.e., before Brush Wellman’s adoption of the 1992 plan.
See Fund Manager v. City of Phoenix Police Dep’t Pub. Safety Personnel Retirement Sys. Bd.,
¶ 18 In their complaint, the Gamezes also alleged that, by breaching its contract with Rudy “to advance its own economic interest, ... [Brush Wellman] ha[d] violated the covenant of good faith and fair dealing inherent in [the] contract.” In granting summary judgment on this issue, the trial court reasoned that ERISA also preempted the Ga-. mezes’ bad faith claim because Rudy’s rights in the pre-1992 policy had not vested before the effective date of the 1992 policy. We agree.
¶ 19 As a general rule, the law implies a covenant of good faith and fair dealing in every contract.
Enyart v. Transamerica Ins. Co.,
¶20 Finally, the Gamezes contend that the tidal court erred in imposing sanctions because Brush Wellman’s offer was “[a]n unapportioned joint offer that encompasse[d] multiple parties [and] claims[, and as such, was] insufficient to support an award of Rule 68 sanctions.” Although Rule 68(d) provides that “the offeree must pay, as a sanction,” the offeror’s costs when “the judgment finally obtained is equal to, or more favorable to the offeror than ... the offer,” this rule does not apply when an offeror fails to apportion a joint offer of judgment.
Duke v. Cochise County,
¶ 21 Brush Wellman made an offer of judgment in the amount of $50,000 plus $25,000 attorney’s fees before summary judgment was entered, an offer the Gamezes rejected. Brush Wellman argues that the trial court properly imposed sanctions against the Gamezes because it granted summary judgment for Brush Wellman on all claims and, pointing to
Sheppard v. Crow-Barker-Paul No. 1 Ltd. Partnership,
¶22 In Sheppard, the trial court properly imposed Rule 68(d) sanctions on a defendant for failing to accept a single offer of judgment even though the offer represented a minor son’s personal injury claim and his father’s claim for the expenses he had incurred in securing medical treatment for his son. In upholding the award of sanctions, this court reasoned that Duke was inapplicable because the father’s and the son’s claims “are ordinarily two aspects of an individual personal injury claim, ... and were divided solely due to [the son’s] minority.” Id. at ¶ 58. Because Sheppard does not apply here, we follow Duke and vacate the award of sanctions.
¶ 23 Affirmed in part; vacated in part.
Notes
. As the court explained, “[H]andbooks can include a variety of non-promissory information for employees: the company's mission, employee guidelines, ... and benefits. While a handbook generally promulgates company rules, mostly non-contractual in nature, only a few substantively govern the employee's job and employment expectations.”
