Maybe you should read the article - the argument was that while yes, perks were offered as a reason to accept a smaller wage, they were then gradually eliminated without changing the wage.
Since when were they eliminated? Have you been to the Google campus? The free food is still there and it's still better than most cafeterias that you have to pay for.
Again - please read the article. This lady is writing about how free food was offered to her in exchange for a lower wage and was then gradually eliminated (which is different from completely eliminated). So yes, from what that lady writes, free food is still there, but less so than when she accepted it in exchange for a lower wage.
I never claimed to add any original research - just that the person I replied to hadn't read the article.
Sounded like it was a raise on top of whatever else they got. I'd take that kind of raise for fewer perks. They could have just as easily not given it.
