My previous comment had asked this also: Is it okay for a company to offer and employee more than they are making at another company or is that a gross and extortion mentality as well?
In my eyes employees are paid based on their worth to a company. If company x says I am worth more than company y, but I like working at company y more, is it gross and wrong for me to say "hey company y I really love working for you but I think my labor is worth more than you are paying me. For example company x has offered me more money of the same job responsibility."?
I in no way have a extortion mentality. Rather I believe I am being under compensated for the work I do and to show this I have gotten quotes for what my skills are worth to other companies in the field.
I would equate the above to shopping around for quotes for a home upgrade. Typically people want to get multiple quotes to see what the fair market value of the work is.
