Take the following term in an employment agreement for example:
This Agreement constitutes the entire Agreement of the parties with respect to its subject matter and supersedes all other Agreements between parties. The parties stipulate that neither has made any representation with respect to the subject matter of this Agreement except such representations as are specifically set forth in this Agreement.
If a prospective employee asks a question before signing, such as "do statutory holidays count as paid time off?" and the employer replies "yes", does the above integration clause nullify the employers "yes"? If the employer does not pay for holidays, does the employee have a case?
When it comes down to it, don't contracts never exist in a vacuum in the sense that context always matters? For example a truck rental it would be implied they would provide the keys to start the truck, even if the term is absent in a written contract that has an integration clause?
