If any, which positions below could be more sustainable against layoff at Cisco. Consider age 50, hardworking and motivated employee:
I imagine 1) and 3) are very vulnerable.
It seems number 4 is a timing bomb? Problem is that folks work in a mix of business and technology. If one gets laid off, it becomes discrimated by network engineers as a “marketing guy” and perceived as a “techy” by managers.
If one has the personality for 5), certainly the most stable till retirement.
