I have been a dedicated employee but have a short duration with 4 separate employers due to the company being purchased. Divisions or my position were eliminated. This in conjunction with my age ( 56) makes finding a potion where I can contribute very difficult. I am working hard at finding a position but almost at a point of starting my own company despite limited funds. Any advice? Was considering putting re-organization or realignment by my end date on resume(s). Identifying short duration and reason in cover letters?
