Sometimes things change without prior notice and some management changes their mind often. Though I personally did not experience issues with supervisors or managers, I have heard from other employees that there are multiple strong personality clashes which made the workplace a bit unbearable, especially hearing about the drama every day. It is also a bit disorganized working there. They are currently still trying to convert from paper documentation to computer/online. Their systems are old and sometimes, people who work there for many many years still have somewhat old way of working thinking, which isn't always the most efficient way of working.
