Be Careful, some things ain’t what they seem.
One particular department has an impossible and tyrannical situation, lots of problems, trust issues, lip service, unable to engage staff, communicate and collaborate. Overall the one questionable departmental could improve their values, ethics, integrity, and management performance. This place has very unique problems that won't be resolved until they change the management regime within the department in question. Some jobs are un-manageable and this may be one of them. Be cautious and do your industrial networking prior to accepting an offer, otherwise, you may find yourself in a bad situation.
