So I'll preface this by saying I fully understand that 12 hour days for 14 days straight isn't the best option for everyone but for the last two years I've been on shiftwork my mental health has skyrocketed.
Getting two weeks off a month feels absolutely incredible. It gives you time to actually focus on hobbies and enjoy time outside of work. Especially here in the UK where you get entitled holiday days on top of this.
I'm not saying it should be the norm but far more industries should have the option of this rather than it just being a strange outlier job.
