I work for a medium to large company here in the U.S. that many, if not most here would recognize by name. Just last week a building that I spent 5 years working in was closed because of asbestos contamination in the air ducts. It was supposed to be closed from last weds (12/1) to 12/6, but apparently they found more contamination and it now looks like the building will be closed until the end of the year (at least). I don't know any details regarding how much asbestos was found, but Im assuming that since the building was scheduled to reopen on the 6th and now wont be opening until the end of the month that it is not an insignificant amount. The company is not being very forthcoming about it, they have made no effort to contact either current employees that used to work in the building, or to contact former employees who used to work in the building. As a current employee who used to work in the building I only found out about it through the grapevine. Any suggestions on what to do about this, if anything?
