Lack of visibility in regards to pay bands and pay in general.
Annual increases, are not a regular practice for those in Customer Support roles.
Vague reviews and a lack of understanding as a whole from the Support org on pay increases based on performance.
Managers in level 2 positions, (above the support team manager level 1) -- they typically are hands off and the average member does not know them or have opportunities to get to know them. So, while your manager level 1 -- is your advocate/mentor, manager level 2 will be providing approval on promotions and increases based solely on KPIs and your manager level 1's ability to advocate.
