5 years ago my Dad passed away. 5 months ago my Mother passed away. My Mother always insisted that there was an insurance policy that Boeing was supposed to pay her after Dad passed away. Dad had retired early due to health reasons. Back in the early 70's respirators were not used in the shop that my Father worked in. (Tool and Die) My understanding is that everyone that worked in his area has since died due to complications brought about by Boeing not using precautions that should have been taken. I need to know - how to proceed on whether Boeing had left Dad a policy, and why they didn't inform my Mother about it.
