Also work in a life sciences company in Cambridge. We went from this rollout of 'come in if required as part of your job' to whispers this year about mandated days back. We lost some benefits over the pandemic that had nothing to do with remote work, so it initially felt like their rollout was to bandage that. Now they're taking that away, most likely next year, and I have a feeling we're about to see a mass exodus. Anecdotally, my team has a lot of people who had 2-3 hour round trip commutes before and I really can't see them going back to wasting that time instead of spending it on their families on a C-suite whim.
