Dear Sunil
It depends upon the type of insdustry say we can divide our industries into 2 parts.
1> Manufacturing Sector ( mechanical/electrical/electronics/pharma) mostly labour oriented & dominated industry.
2>Service sector (IT/ITES/KPO/BPO/Broking firms/Research Firms/Banking/Insurance/Hospitality/Airlines etc)
HR people are having their true requirement into point 1 companies where there are hughe problem like labour problems, staff problems ,union level issues,strikes etc.
HR people just come for enjoyement in point no2 companies, in my 5 years of career into S/W insdutry i never found anybody working hard & late after 6PM.They only came with good make-up,short dresses & specially with lot much to eat, They always sit into canteen for more than 1 hour during lunch break , again for tea break again for snack break, total 3 hours wasted, 1 hour they stroll around all cubicle making some PJ about page 3 people,They don't have challenging job to do as all are too much educated & do not blame HR, appraisal time is also very smooth for them just saw the face of employee & then if they found him smart, good looking, wooing behind them then make apprisal , if they don't do then still no worries at all since professional never come up & hit you or curse HR people,no responsiblity, no tension just come to office eat tiifin, do all time blah blah blah & sharp 6.0 clock not 6.05 also to go home pretending they are handling all organisation
But in manufacturing sector union people shows them starts in a day, when they say a single word union people say 10 slang, Union people know how to handle these HR people very well, Here pressure is too much people directly slang to HR,even in strike perioed mob hit the HR people ouside company premises, they make life of HR peole like HELL comes to ground.
