Pros
The pros are few and far between. The best thing I could say about working for Westlake is that every so often they bring in food trucks on Fridays.
Cons
First, Westlake claims to care about their employees. This is false. They have multiple offices, but if you work in one away from the corporate office in LA, the company treats you as if you don't even exist. Second, they hide their true policies regarding ESOP plans and PTO. They do not pay out PTO, even if you give a two weeks notice that you work. This is a choice on their part. I worked for them for over a year and a half, only taking off a couple hours here and their for doctor's appointments, and my hard work and loyalty to the company was not rewarded. When I left, they chose not to pay out my 43 hours of PTO/sick time I had chosen not to use to provide hard work to the company. Finally, outside of IT, the managers are brutal. In any department. They require 200% of your effort to get the job done, but micromanage your every minute of the day and write you up when you are unable to complete daily tasks because you were stuck in their meetings or trainings.
