Integration clauses can stop employers enforcing terms scattered across hiring docs
A Michigan court blocked an employer from enforcing a six-month lawsuit deadline in an employment application that the employee's contract prohibited adding.
The Michigan Court of Appeals delivered the decision on February 17, ruling that Acrisure Wallstreet Partners cannot enforce a six-month deadline for filing claims that appeared only in an application form, not in the actual employment agreement the company later gave Ty Mayberry to sign.
The case turns on a scenario familiar to anyone who has run a hiring process: a new employee signs multiple documents on their first day, often within hours of each other, creating a paper trail that can later prove messy to untangle.
When Mayberry accepted a job as Worksite Director at Acrisure Wallstreet Partners in 2018, the insurance brokerage subsidiary required him to complete two separate documents. First came an employment application, which buried a clause requiring him to file any lawsuit about his job within six months. Later that same day, after attending several meetings, Mayberry returned to sign his actual employment agreement.
That agreement said nothing about shortened deadlines. Instead, it declared itself the final word on the terms of his employment, stating it "supersedes any and all prior employment agreements" and cannot be changed except through a written modification that specifically references the contract.
The trouble started in March 2019 when Mayberry and the company's CEO, Leroy Wilbers, signed what they described as a modification to Mayberry's compensation and employment terms. They kept it secret from the rest of the company until February 2020, when Mayberry presented the document. Acrisure Wallstreet Partners refused to honor it, and Mayberry's employment ended.
When Mayberry sued in January 2021 for breach of contract, the company pointed to that six-month deadline in the application and argued his claim came too late. The trial court disagreed, and Acrisure appealed.
The company made two arguments. First, it said the application and agreement should be read as one document since Mayberry signed both on the same day as part of the same hiring. Second, it claimed the time limit didn't conflict with the employment agreement because the agreement stayed silent on deadlines.
The appeals court rejected both theories. Judge Matthew Ackerman explained that while courts sometimes read related documents together, they cannot override a clear statement that one document represents the complete agreement and blocks additions from outside sources.
The court noted the employment agreement explicitly prohibited anyone from adding terms unless they followed specific rules: a written modification signed by everyone that directly references the original contract. The application did neither.
Even the corporate structure created problems for the employer. The application was technically between Mayberry and Acrisure, the parent company, while the employment agreement ran between Mayberry and Acrisure Wallstreet Partners, the subsidiary. Michigan treats parent and subsidiary companies as separate entities.
The company tried arguing that the six-month limit applied only to the application process, not the employment itself. The court found that argument hard to swallow, pointing out the clause covered "application for employment, employment or termination of employment." That plainly governs the entire employment relationship, making it a term that should have been in the main contract.
The decision carries a clear message for human resources departments: if you want to enforce a provision, put it in your employment agreement. Scattering important terms across multiple documents creates gaps that integration clauses will only widen. When a contract says it represents the complete deal, courts will take that language seriously and refuse to import terms from other paperwork signed during onboarding.
The ruling suggests employers should audit their hiring packets to ensure critical provisions appear in the right places, especially when employment agreements contain integration clauses that wall off supplementation from other documents.
