“There are too many other variables that constitute salary other than purely the monetary, though it is a tallyable number that is easily digested. Allowance of part time, maternity leave, FMLA, etc. all add up as favorable to both parties but utilized far more often by females than men. Flexibility is a major benefit and can be considered to have a monetary value, though less clear than an hourly wage; still very important and more of use to women than men, so far.”
