A while ago I had to pick between a few post-doc offers. I ended up choosing one in a modestly interesting project hosted by what you'd call a high-profile university, with seemingly strong PIs (decent citation counts, many annual publications in top-tier conferences) that I did not, however, know in person.
From the very get go of my employment, I got weird vibes from my host university and the local group. I found no group cohesion, common research agenda (other than vaguely following the latest research trend), or basis for collaboration. There was an excessive amount of less senior colleagues working basically on their own, with the local PI being at times unable to even recall individuals' names.
With respect to the project itself, I quickly realized there was very little idea (if any) on what to actually do, what the challenges and/or the opportunities were and how go about them. Despite this, there was an almost immediate push for publishing "something". Meetings between myself and other project affiliates quickly started going sour, with ill-guided suggestions, condescending tones, etc. This strongly demotivated me, at which point I started pursuing other (external) collaborations while tying loose knots. This proved relatively fruitful and gave me peace of mind for a while (subduing both the impostor syndrome and the feeling of "wasting my post-doc").
However, this didn't sit well with my superiors, who are dissatisfied with my work (or lack thereof), and reasonably so. I tried finding ways to make ends meet (intermediating between the people that actually want to work with me and the people that just expect something of me), but to no avail. It seems to me that such collaboration prospects are being dismissed for purely punitive reasons regardless of their possible merits. It was communicated to me from my PIs that I am to work alone from now on, except for their supervision.
At this point I'm wondering what's the best way forward. I am strongly in favor of quitting ASAP. This won't deprive me of income, as I have secured a number of (far better paying) industry offers as a backup plan, at least until I get to find another academic position. Meanwhile, a part-time industry job should allow me some time and the "liberty" to keep some lines of research open (done of my own volition at my own time with people of my own choice). Ethically this is absolutely in line with my personal moral compass; I think this is the "honest" thing to do, and have a strong disdain for the kind of work conditions that I am subjected to. I don't see the potential of feeling any kind of remorse/guilt from a work-ethics perspective. I'm wondering, however, whether this might bite me in the ass a few months/years down the line (even though I can't exactly imagine how). Another, more sinister/cynical, part of me believes that I should keep this going, pursuing any opportunity for fruitful collaboration/investigation I currently have or may stumble upon in the future, while doing the bare minimum to justify my contract not being terminated -- thus no odd timings on the cv, plus a constant stream of publications bearing my name. I'm certain that the latter option will however be difficult for me to manage in the long run, and might backfire in multiple ways. What should I do?
