Caller ID said "Unknown Caller."  Male caller calling asking for the office manager, offered safety and labor law posters at outrageous prices.  Typical workplace poster scam.

Caller asked for who was in charge of our safety program, told him we
didn't have one that there are company rules and we have to follow them,
then he asked for the name of a person who has never been with our
company and when he asked for whomever was in charge I told him he had
still not told me who he was or who he was with.  Gave me his name, and
said he was with "Safety Services Co." in the meantime I was Googling
his number.  Told him I would put him through to the Safety Manager but
there would be no name on that voice mail as we no longer give it out
per company policy and dumped him into the scammer voice mail.  He left a
message saying he was Howard Jones calling about our state and federal safety requirements and he
could be reached at 888-619-5799 which ties back to a safety poster scam.
