As much as I hate the culture of linkedin, it’s useful in situations like these. A few years back my job suddenly wanted me back in the office, and a friend of mine suggested making an account on linkedin. I immediately started getting headhunters contacting me, despite the fact that I’m just a lowly estimator at a medium distribution company in the construction sector, and within a week I had a job offer lined up for a fully remote position with a competitor. I used it to negotiate an almost-entirely remote position (I still come in once a month for a department meeting) and a significant pay raise. I thought it’d put a target on my back to stay where I was, but I haven’t had any issues so far, and I still get plenty of people contacting me on linkedin in case something does change.
