IT department is the most unstable and mismanaged department due to:
(1) arrogant and dishonest managers that no one respects
(2) inexperienced managers that create more problems than they resolve
(3) lack of trust in management due to their complete lack of transparency
(4) frequent resignations by frustrated and disappointed employees that see no future for themselves in their current positions
(5) frequent firings of hard working and qualified employees for expressing an opinion that differs from that of management's, only to be replaced by unqualified and inexperienced people
(6) rampant favouritism and scapegoating
HR department is unable to treat employees with dignity, and is run by a duo of inept managers. They spend most of their resources on unimportant projects such as: which flavours of ice cream to serve at the next company function, and new ways to solicit "anonymous" feedback from employees to use against them later. This department is often used to threaten and silence employees.
Senior management is unwilling to fix the problems listed above by replacing the incompetent management in IT and HR. This will only serve to put the company at risk.
