Met up for work, raising pace (5)
I believe the answer is:
tempo
'pace' is the definition.
(I know that pace can be written as tempo)
'met up for work raising' is the wordplay.
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'for' says to put letters next to each other.
'work' becomes 'op' (abbreviation for opus).
'raising' says the letters should be written backwards (in a down clue, letters go up).
'met' back-to-front is 'tem'.
'op' reversed gives 'po'.
'tem'+'po'='TEMPO'
(Other definitions for tempo that I've seen before include "Muscial time" , "Speed or beat, musically" , "Rhythm or speed as in music" , "Metronome output" , "Rate and rhythm in music" .)
