A colleague of mine in the recruiting field shared this excerpt from the cover letter sent in by a prospective job candidate:
My salary requirements are based on what's required to provide shelter and feed my family and will require some added perspective about what it is you require.
Good of him/her to add the afterthought signaling some willingness to consider factors beyond living costs, I guess.
Unfortunately, as my colleague noted:
...since the law prohibits asking about someone’s family size, composition or economic status during an interview, this line in the cover letter means that the candidate can receive no further consideration.
P.S. If this cover letter came from you, please (please) see my post on Cost of Labor versus Cost of Living.
