Now-a-days in a large business house, office manager cannot perform all the official duties alone. He has to delegate his power to his subordinates and these subordinates are called departmental managers. Office is the central nerve of the organisation and as such, the general manager must be in touch with each departmental manager. The departmental managers look after the clerical operations of his department.
There should be full co-operation between the general manager and the departmental managers. The general manager cannot function well without the co-operation of the departmental managers. The departmental managers should keep the main office informed about the functions of their departments. Because of this co-operation, various managers must take the office manager into confidence whenever any major decision is taken. For this reason, it can be viewed that general manager should be a specialist and he should be the incharge of clerical work in the general office and departmental office.
