How do I pay Bangladeshi-based Virtual Assistant & setup his payroll?

A lot of the decision involved in this depends on the job functions and sometimes, the state you are located in. There are many legal issues surrounding hourly vs. salary. There is "salary-exempt" and "salary non-exempt". Exempt employees don't receive overtime pay; nonexempt employees do. The classification criteria for exempt and nonexempt workers are part of the Fair Labor Standards Act, or the FLSA, which is the federal law that governs minimum wage, overtime pay and working hours. The general federal guideline is that if an employee is not managing or supervising, he/she must be paid hourly. There are exceptions to this for certain sales and other professional positions; however, use caution as there have been many successful lawsuits against employers over the years for abuse of salaried positions. I would recommend you first make the determination as to how to legally classify your employees, then consider the impact on service culture. Feel free to contact me to discuss this in further detail.

What are the company's policies regarding the frequency and timing of employee reviews? Start by checking your employee handbook and make sure you completely understand the policies. You then have a decision to make: you can approach your boss to discuss the matter and try to work it out, you can talk to your HR professionals to ask them to address it on your behalf, or you can wait and ask if any adjustment to your compensation can be made retroactively, in light of the delay. Each strategy carries risks. The first two risk impacting your long term relationship with your boss. The last strategy is a financial risk but preserves the relationship. You have to ultimately decide what's most important to you, and what consequences you're willing to live with. Happy to talk with you directly if I can be of more help.
