Kontras
1) Upper management making decisions without regards to the employees that are affected by them. 2) Very big - so big that it's hard to change things quickly. This is a big company - so individuals get lost in the big corporate environment. Listen, this is a tough economy so yes money is a focus. It's a business and needs to make a profit. However, decisions are made that seem to not to take into account that employees are actual people sometime. This is generally does not apply at the office level, but above that.
