Well, there is something, that we as humans tend to ignore a lot of benefits that come along with an employment. Having spent around 9 years now in the industry, am sure it has to do with the individual culture and more so, perception of the candidates, when it comes to making a choice between comparable baseline packages with different benefits and incentives. The perception arises out of "Not sure" thinking on part of candidates as to whether they would actually be earning the benefits or it is a mere eyewash to project a better package. This stands true for incentive based benefit component in the compensation package. In addition to this if a candidate is sure that he would be earning an amount X which is slightly higher than another amount Y though the latter offer has to offer many other benefits, the candidate chooses the former. This is because at the end of the month people definitely go into evaluating everything in monetary terms, i.e, how much amount is transferred in their Salary Accounts.
Thanks!!
