If an employee of a company receives a large inheritance, it will not likely have any direct impact on their job or employment status with the company. The inheritance will likely be considered separate from the employee's work, and will not affect their performance or job duties in any way.
However, there are a few situations in which an employee's inheritance could have an indirect impact on their employment. For example, if the inheritance is substantial and the employee decides to retire or take time off work to manage their newfound wealth, this could affect the company's operations. Additionally, if the inheritance includes a significant amount of stock in a competitor company, the employee may need to recuse themselves from certain projects or decisions that could create a conflict of interest.
