[We] received a call from [operations] warning us of the risk of tail tip on arrival of [a] B737-900ER. We were directed to offload 20 bags from the rear of the aircraft which had 88 bags and 182 lbs of freight loaded. The forward compartment had 59 bags and approximately 1400 lbs of airmail and 1 dog.  Load Planning should not be planning so much weight to be loaded in the rear of these aircraft. They know these airplanes are tail heavy and yet they keep dictating the load plan to be completed in an unsafe manner putting our aircraft; equipment; employees and passengers at risk.  We offloaded everything from the rear before deplaning any passengers and we still saw a significant weight shift once passengers began deplaning.
Ramp worker reported a 'significant weight shift' during passenger disembarkation in a B737-900ER even though they had already unloaded considerable weight from rear pits.
