Cultural differences, employee recruitment and selection challenges, and ensuring career growth and development opportunities were identified as some of the main human resource management challenges for international businesses. HR managers must effectively manage cultural diversity to prevent issues like cultural shock, communication difficulties, and turnover. They also face constraints in recruiting the most suitable candidates globally and selecting individuals with qualities like cultural intelligence. Further, career development opportunities need to be equitable and match evolving technological skills to retain employees in international contexts. Aligning company policies with host country regulations on taxes, compensation, ethics, and sustainability can also help address legal risks.
