I worked at a very large company, which post-merger started rolling out various changes which negatively impacted our development group. $0.25 sodas, redbull, and snacks went to normal prices, release night dinners were cut, flex time became less flexible, etc...
While no one quit due to any one of those changes, it did change the place from somewhere fun to work to somewhere that wasn't fun. As a result about three months later a large number of the architecture group and other key people quit within a 1-2 week span. So while no one may quit the day the water coolers are removed, that type of change will lead to higher turn over later on, especially among the top folks, who can find a new job pretty easily.
