OK I come from a country with another social and labour culture (which is actually often laughed at). Even if one goes for total labour market flexibility, still people should not be treated like that. It's a question of respect for the human being, his/her experience and profession (top engineering), image, overall contribution etc. Especially where such people have contributed so much to the repute, image and success of a business to the extent that the name of the business or its top products were often associated to that of the engineer(s).
All my best wishes accompany you in your future endeavours. And a big thank you for having contributed so much and so brilliantly to the development of audio transducers and the science of sound reproduction. If this is what you desire, I hope you will be able to continue on that path through a consultancy bureau or otherwise.
