Yup, one previous job. Issues with the boss and my colleagues and general unhappiness at the way things were handled in the company meant my performance was dropping. A moment of clarity when it drinking with a mate showed me that a ‘quit or be fired’ situation was the most likely outcome, so I handed my notice in the next day. They accepted it and put me on gardening leave for the month.
I took two weeks off to clear my head, went round some agencies in the third week and had walked into a decent temp job, just to cover the bills, before my month was up. That was 7 years ago, I got made permanent off the back of the temp job, and am very happy where I am now.
