Pros
Depending on the team you are in, it can be very flexible, and you’ll be working with nice people.
Cons
HR needs to step in more, they are supposed to set a precedent yet it seems like the higher ups in different departments actually set the expectations. Which can be toxic, and some managers clearly don’t know how to manage teams. HR seems to be a nice and fun department, but the rest of the company has lackluster reviews.
Also, stop advertising a total rewards package to new hires when you need to work over fiver years to get some benefits and due to the merger they won’t actually get that package. Just raise your base salaries.
