Pros
There were some great people. Old Takeda was a great place to work, great benefits, flexibility, nice office space, good cafeteria. I think they had a great model that worked for their size and company demographic before Shire. Maybe in a year once things settle it will be a great place to work again.
Cons
Once Takeda bought Shire it was very clear leadership was not being thoughtful in the decisions they were making but just throwing out whatever they thought would please 1 or 2 business leaders. The problem is you are too big, complex and diverse now to just please 1 or 2 businesses. Leaders never took the time to understand what they bought. Shire who had just gone through this 2 years ago was completely ignored, there was no partnering, leadership stopped communicating, horrible change management, wasted time repeating information. Leaders seemed to not care as I suspect many of them will not be with this company within 6 mths and very few were willing to step up and be leaders (go against the grain when they knew it wasn't in the best interest of the entire company). A company that is 1/3 the size of the company they just purchased (in US) that made very few changes over the past 15 years is just not equipped to rush in massive changes. Trying to run the US business with the same model as other countries is not going to be successful for the new size/demographic of this company. Some really great, experienced people left the organization which speaks volumes. A huge red flag when you are asking why and how and are just being told superficial responses that show zero understanding of the actual process or that there is any actual thoughtful reason behind the decisions being made. Everything was just at the surface level. Presentations to leadership were skewed and lacked critical information, again surface deep.
