ine ▁in ▁the ▁face ▁of ▁acceler ating ▁infl ation ▁for ▁three ▁main ▁reasons . ▁First ly , ▁w ages ▁are ▁not ▁re vised ▁as ▁frequently ▁as ▁pres cribed ▁in ▁the ▁norm s ▁i . e . ▁not ▁more ▁than ▁five ▁years . ▁In ▁fact ▁it ▁is ▁believed ▁that ▁revision ▁every ▁three ▁years ▁and ▁even ▁alternate ▁years ▁not ▁only ▁to ▁help ▁workers ▁from ▁increasing ▁costs ▁of ▁living ▁but ▁also ▁to ▁improve ▁super vision ▁of ▁the ▁act . ▁Second ly , ▁many ▁states ▁do ▁not ▁provide ▁for ▁dear ness ▁allow ance , ▁a ▁saf egu ard ▁against ▁infl ation ▁and ▁finally ▁minimum ▁w ages ▁are ▁not ▁linked ▁to ▁a ▁cost ▁of ▁living ▁index . ▁ ▁Ex em ptions ▁from ▁payment ▁of ▁minimum ▁w ages : ▁Government ▁projects ▁have ▁been ▁known ▁to ▁resort ▁to ▁various ▁channels ▁for ▁pay ing ▁w ages ▁below ▁the ▁minimum ▁w age ▁rate . ▁They ▁use ▁methods ▁such ▁as ▁special ▁notifications ▁and ▁exem ption ▁clause ▁( 2 6 - 2 ) ▁of ▁the ▁Min imum ▁W ages ▁Act . ▁The ▁parliament ary ▁sub - comm ittee , ▁ 1 9 8 7 ▁noted ▁that ▁w ages ▁of ▁government ▁programs ▁such ▁as ▁N RE P ▁and ▁R LE GP ▁were ▁below ▁the ▁pres cribed ▁minimum ▁w age ▁rate . ▁Many ▁prof essions ▁and ▁indust ries ▁do ▁not ▁fall ▁under ▁the ▁coverage ▁of ▁the ▁act , ▁for ▁the ▁simple ▁reason ▁that ▁no ▁minimum ▁w age ▁has ▁yet ▁been ▁pres cribed , ▁hence ▁employ ers ▁pay ▁w ages ▁on ▁their ▁own ▁dis cret ion .
