Final answer:
For a managerial employee filing a wrongful dismissal suit, the primary legal framework is Contract law, although statutory regulations and common law principles could also be relevant. Collective bargaining agreements are generally not applicable unless the employee is unionized.
Step-by-step explanation:
When a managerial employee is filing a wrongful dismissal suit, the legal framework that would typically apply is d) Contract law. However, it is also possible for statutory regulations to come into play, especially when specific employment statutes are in place to protect workers' rights. Common law principles are often invoked to interpret and enforce employment contracts. It is less common for collective bargaining agreements to be involved unless the managerial employee is part of a union, which is rare for such positions. Ultimately, the specific circumstances of the case will determine the applicable legal framework.
