I resigned a few months ago from my first post-graduation position as a lawyer in a major public institution where I had previously interned. When I arrived at the job, I started helping senior-lawyers as my main task. After an atypical re-shuffle, I —still the newest hire— was handed an entire senior-level portfolio while also being required to keep assisting every colleague in the unit. My deputy head then began sending me (and only me) on out-of-state trips without coverage, leaving my own files untouched. Workdays stretched past twelve hours as unfinished tasks from others were routinely left on my desk. When I flagged the overload, he blamed my competence; when I took certified medical leave, he publicly threatened to replace me. For all the above, I then began to take my time, if I was already the last to leave, I started to clear myself talking to my colleagues time to time, to go out and smoke a couple of times and arrive 10 or 15 minutes later than usual (also taking into account that the official entry time was at 8 and my boss could arrive until 10, then he made us arrive at 10 and, therefore, leave later), but always finishing my job; things that did not seem to my boss and he started complaining about them. Exit negotiations turned hostile, and I ultimately chose health and dignity over an unsustainable role.

Now, after a couple of months, I need the job back because of economic and personal problems. I would not be with the same boss, but in order to get the job back, I would have to talk to my former boss first, because she will be asked if my job was good while I worked with her and if she had any problems with me.

Any recommendations to talk to her?
