I responded to an online “job posting” and received a very slick automated reply. However, it went into some detail about the company's products and business model, which is generally not the case with other 'work at home' schemes I've looked into. I replied with a few questions, and received a prompt response which answered all my questions completely and without deceit. Here's what I learned:
Recruits are obliged to buy a $20 annual subscription to online company support. You are also required to cough up a monthly fee which will dictate the commissions received on member recruitment and product sales. That fee STARTS at $50/month.
While I applaud them for being straightforward and reasonably transparent, an employer should pay the employee – not the other way around. The other way around is about as sketchy as it gets. If you jump into this and get burned, it's your own fault.
