Step-by-step explanation:
The student's question pertains to labor laws and employment contracts, specifically in the context of what another company, Budget Pipes, is allowed to do in relation to an existing employment agreement between Zach and Affordable Plumbing Supplies Company. In the scenario provided, Budget Pipes can offer Zach a higher salary, assuming there aren't any non-compete clauses or other legal barriers within Zach's current contract with Affordable Plumbing Supplies Company.
