Managerial accounting It is a common feature in any concern that some employees leave the concern and others join it. Workers change the job either for personal betterment or for better working conditions or due to compulsion. Labour turnover is the ratio of the number of persons leaving in a period to the average number employed. It is the change in the composition of the labour force in an organisation. It can be measured by relating the engagements and losses in the labour force to the total number employed at the beginning of the period. All the losses must be taken into account regardless of the cause for leaving.
