hi,,
atrrition rate calculation is little bit different than wht is mentioned here ... i will soon post the correct method of calculation..
you can also concentrate on reasons for atrition and also give the firm some suggestions to reduce the atrrition ... .. also concentrate on the consequences of atrrition anf finnaly the hidden aspects of attrition.. for e.g some amount of atrrition is actually healthy for organisation.. jack welch principle in restructuring genral motors was every year remove 20% of dead wood and recruit fresh blood... so this is the positive aspect.. and atrrition and availibily of jobs are related .. unless there is attrition there are on job availibilitie and when there are job availibilitie there is attrition ...
