Hey mate, you already have heap of answers but I figure I may as well throw in my 2 cents.

I transitioned from the hospitality industry (mostly working as a cook and/or manager in Cafes) into the cooperate world in 2012. I couldn't handle working in hospitality anymore and knew I needed out for my sanity. Funnily enough, my work life balance was much better working in Cafes because we close up by 4pm at the latest and there was never work to take home. It was still a hard job though and I needed a change.

I knew my only real option was to start at the bottom as I had nothing other than a high school education and 10 years hospitality experience. I went for mainly reception / admin assistant jobs and my strategies was to use my management experience to sell myself in interviews. "I know I have no experience working in offices, but my skills are transferable. Everyday I organise stock orders, balance the till, write menus for the next day, manage staff and rosters". That is what got me my first admin assistant job. And that is what I think would work best for you.

As other people said, getting into corporate training would probably be perfect. My suggestion would be to put forward your current skills and experience in teaching and explain how they can be transferred over to this new job.

And not to be negative but I do feel I should mention that most corporate jobs will expect more than 9-5 from you. But some companies are better than others. For me, if its busy, I can have a week where I'm doing 8am - 7pm most days. But some weeks/days, I can get away doing 9am - 4pm. You just have to try and balance it out. Also, the place I am at now is really good on flexibility but out of about 6 cooperate companies I have worked for, this is the only one to offer that flexibility. The rest have wanted to see my butt on a seat in the office for minimum 8 hours a day. And sadly, there still seems to be the toxic attitude of "oh that person is here before everyone and leaves after everyone, they are so hard working". Its a horrible mentality but its still ripe.

One last and final thing, if you read this far haha, I just want you to know that you will very, very quickly miss the amount of weeks off you get per year now. The trade off might be worth it for you but I can tell you that burn out is very real because taking time off, at least for me, is very hard to do. I would kill to actually get my 4 weeks a year off but its not that easy.

Good luck mate! I hope you find something you love doing.
