This clue might be a double definition.

'get on' is the first definition.
'shift' can be an answer for 'get' (thesaurus). I'm unsure of the 'on' bit.

'change of position' is the second definition.
'shift' can be an answer for 'change' (shift is a kind of change). I'm not sure about the 'of position' bit.

'with' acts as a link.

Can you help me to learn more?

(Other definitions for shift that I've seen before include "Change position" , "Move; garment" , "Move; straight dress" , "Move (fast!)" , "Dislodge" .)
