From several reports, here's what I have on AstraZeneca's plans in Waltham: they've told people there that cuts are coming. But they haven't gotten very specific on when, or who, or how many. All those questions (that is, all the questions there could be) are under review.
Pfizer has done this to their people before, as have other companies in the throes of layoffs, and it's the only way I know to actually push morale and productivity down even further in such a situation. You come to work for weeks, for months, not knowing if your, your lab, or your whole department is heading for the chopping block. All you're sure of is that someone is. And will your own stellar performance persuade upper management to keep you, when the time comes? Not likely, under these conditions - it'll more likely be the sort of thing where they draw lines through whole areas. Your fate, most people feel at these times, is not in your own hands. A less motivating environment couldn't be engineered on purpose.
But that's what AZ's management has chosen to do at their largest research site in North America. I hope that they enjoy the results. But then (and more on this later), these are the people who have chosen to spend billions buying back their own stock rather than put it into research in the first place. It's not like the score isn't already up there on the big screen for everyone to see.
Update: as mentioned in the comments, this does at least give everyone a warning bells, and a chance to explore other options, as they say. And that's true. AZ employees, though, have been seeing nasty cuts for a while now, and have been well aware that they're not in a stable environment. It's hard to make the decision to leave, but there have been plenty of chances to think about it in the last two or three years.
But I was actually arguing against the company's Waltham strategy from the viewpoint of upper management, on their terms. It's better for employees to have some warning, but I think it's better, for a company, to cut if you're going to cut, and get it over with. If you say that deep cuts are coming, you should do the actual deed as soon as you can. Then you tell the departments that are left, "OK, the storm has passed. Let's try to turn this thing around". But this current situation is the worst of both worlds. "All right, people, here come the big cuts: this site's closed, that site's closed. But your site, well, we don't really want to close it, but we still haven't had time to work out how much to shrink it. Yeah, this was supposed to be the big announcement, but it's just been really busy - you know how it is. We're going to get around to you. Pretty soon. And pretty deep. But we don't know which parts to lop off, not just yet. Back to work, everyone!"
