Tesla/Musk.
Back in 2014 Tesla and Ecotricity had an agreement to upgrade Ecotricity’s charging network to be compatible with Tesla’s superchargers. Tesla whined that it wasn’t being rolled out fast enough. Ecotricity wasn’t a very big company and was basically working for free, so asked Tesla to actually support the roll out if they needed it faster. Musk went mental has been trying to destroy the company ever since. The 2014 Tesla patent release was never about collaboration or saving the planet, he just hoped somebody, somewhere would use it to undermine Ecotricity.
Join a union and ask for their advice. Even if there’s limitations on what they can do as it seems the process has already started, they’ll still be able to advise on what you’re able to do deal with constructive dismissal.
Look for another job. It’s way easier to find work when you’re in work and don’t have to explain why you’re not at your last job.
Do both of these things. Your health isn’t going to benefit working at a place where you’re not wanted, even if they can’t just fire you.
Oh and if you’re in a country where you’re allowed a representative in meetings and you can take one, always have your union rep there, no matter how friendly it seems.
