Distinguish between mobility of labour and division of labour.

Mobility of labour refers to the ease with which labour can move from one job to another or activity to another or from one geographical area to another when there is a change in the conditions in the labour market; whereas

Division of labour  is the  allocation   of tasks  (activities)   among  workers   in the  production   process   such  that  each worker   is  given  a  task  which  he/she   can  perform   best.
