Final answer:
The reduced influence of foreign nationals in a home office can be attributed to increased globalization and competition, outsourcing, a shift from manufacturing to service industries, and weakened unions due to workplace protection laws and potentially less supportive U.S. union formation laws.
Step-by-step explanation:
The reduced influence of foreign nationals in a sales force within a home office can be attributed to several key reasons. Firstly, the globalization of business has considerably increased competition from foreign producers, which has encouraged companies to outsource work to reduce costs. Secondly, there has been a shift from manufacturing to service industries, which changes the dynamics within the workforce and reduces the dependency on traditional sales roles. Thirdly, because of the workplace protection laws that are now in place, there is a reduced desire for unions, diminishing the role unions play in supporting and influencing positions held by foreign nationals within a company. Finally, U.S. laws are potentially less friendly towards the formation of unions compared to other countries. The combination of reduced union support, the changing landscape of the industry, and the cost-cutting measures through outsourcing are likely to diminish the influence that foreign nationals have in a home office.
