Pros
Good salary and benefits package. Excellent job security (they're not exactly going out of business - it's the second-largest electrical utility in the U.S.).
Cons
A stodgy, top-down company culture in which the manager is king and his authority goes unchecked. Independent thinking is discouraged here - anyone who suggests something new or doesn't conform to the thinking of the department as a whole is looked upon as "difficult to work with" or negative. SCE is stuck in a 1950s mind-set, mainly because a large percentage of the employee population has been with the company for decades, and old habits die hard. This is a dark, negative place to work in which employees talk the talk but don't walk the walk, and company values are just words on paper. There's a reason why SCE offers such a generous compensation package: the company culture would drive away employees, and it's easier to keep them with high salaries than it is to fix the problem.
