This company repeatedly sent me mail and call me after at least 4 phone calls to ask them not to. They pose as a government agency that regulates the posting of up-to-date labor law signs within the workplace. They charge ridiculous amounts for the signs (way above market), and threaten people that don't purchase the signs from them that they may be fined and are not covered by the law.
In a nutshell they use extremely predatory marketing with a fear-based campaign all under the guise of an "official entity".
You do not have to purchase your labor law signs from these people, they are an independent high profit company. The sign are much cheaper elsewhere. Beware of their persistence and scare tactics and do not be fooled.
yours in health and good business practices!
