Thinking of going down the route of stress, current employer has fucked me over and moved my place of work along with not covering travel. I want out, but finding a new job will take some time and I can't afford to be 4k a year worse off based on travel costs, so I'm thinking of getting signed off on long term sick as my employment contract covers me on full pay for up to 6 months, what would be the best way to go about it?
