Harsh Leave - Avis employé Scientist AstraZeneca

Ever since the re-organization from Medimmune to AstraZeneca, I felt that there were no growth opportunity and that the higher ups were more focused on promoting themselves rather than leading the team. I also had the worst company leave experience, where instead of the managers asking me for my data, they went through the HR. The HR told me I could leave a week early from my last official day in exchanged for the link to my data. When I kept asking the HR for this to be written in an email, HR threaten me that I would be escorted out of the building and that they will not provide me anything that I could use against company. Feeling uncomfortable and threatened, I gave them the data, and they deactivated my badge before I could return everything to the company. Really upset about my leave experience after 5.5 years with this company.
