Very poor HR and people management. Current HR is incapable of managing technology people and unable capitalise on thier full capacity. A "Us an Them" mentality, rife with standover tactics and intimidation which stifles innovation.
Horrible location in middle of nowhere, far from everywhere. 1/2 hour lunch, clockwatching HR, no flexibility. Very unplesant, even if you put in extra effort. Upper management always interfere with technical approaches and are simply not qualified to do so anymore.
You get an award for how long you can deal with the stress.
