Ventajas
Well Paid, Flexibility in Workplace (which means you can go to the doctor when you need to, but you have to get extra, special permission to work from home, even when fuel prices are over $4 per gallon), solid security and control measures. Global work and workplace opportunities.
Desventajas
Clandestine management decisions, including career choices, "command and control"-style management, inconsistency (we need new ideas, but can't get beyond year-2000 thinking), low-level leadership panics due to overbearing (and out-of-touch) senior management, lack of vision, lack of stated goals, lack of communication, management immune from hearing feedback from employees due to forced ranking, conducted by supervisors needing the feedback, that determines ones employment status from year to year -- because retribution is always a possibility, despite the controlled nature of the process.
