There are two particular issues I have with the lab. The first is how the lab chooses to promote employees. In each of the three years I have worked there, after my 'substantial' raises each review period, my take home pay decreased. While I was getting a ~3% raise, the tax increases and health care increases grew at a higher rate. In addition, there is no particular way to get a raise other than getting a new degree, in my case a PHD. The other issue is location. If you are a fan of Massachusetts, this does not matter, but Boston has worn me out. Not getting paid appropriately and living in a place I don't really like have become a bigger burden, out weighing my enjoyment of my work.
