I am not sure, but Pfizer does have a huge facility in eastern Connecticut and I found out something very interesting about Pfizer a few years ago, while involved in a lawsuit brought by a Pfizer employee who worked at that CT facility. They are one of these companies that recruits overseas and raids overseas universities of their top graduates. The plaintiff in that case was a highly compensated person at Pfizer who graduated valedictorian of their class at a well known European university. Pfizer had paid all costs of the employee's relocation to the USA, paid for attorneys to get green card etc as well. The large investment banks in NYC do exactly the same as Pfizer. They go to McGill in Quebec, to other countries best universities, and offer top dollar salary and relocation costs plus costs of getting the green card etc. Simply put, they raid and buy away the best and brightest at foreign universities, who usually come cheaper overall than the same graduates from Yale and Harvard who have steeper financial expectations on salary and greater loan debt. One of my clients who works at one of the investment banks and comes from a country in South America (at which the client was valedictorian of the top university in that nation) described this process by which she was wooed and financially seduced. It was quite interesting to hear.
But we are talking about people making well into 6 figures or more at advanced positions with these companies. And in the case of Pfizer they know who is working on clinical trials and doing great work overseas from the chemists to the stats and math majors needed for trial data presentation. They target people who are still doing clinical work in school and go after them hard.
This is the power of Big Pharma and the power of Wall Street in action - they buy away talent wherever they can find it.
