Pros
A good starting place to learn and then get the hell out, and fast. Minorities are not messed with as much, HR is scared to death of (more) lawsuits. Stock is going up thanks to the pimple-faced MBAs at Boston Consulting Group who helped ABM effect the layoff of over a hundred long time top performers.
Cons
As a former senior leader within the company's executive group, I can say that this company has no regard for any of it's people and will burn anyone and everyone to give the perception of success to the shareholders and Wall Street. The company is now completely run by the Janitorial cronies and they are doing everything they can to fill their own pockets with stock and bonuses before this gravy train for them goes over the cliff. Most of them are at or near retirement age and do not care about the long-term benefit of company, it's people or mission. Sad to see this happen to a 100+ year old company and I'm sure the founders are now rolling over in their graves.
