I watched the video Ethical Dilemmas in the Workplace: The Ethics Guy on ABC News
If I was the interviewer and found out the interviewee had been fired from their last job, the first thing I would do would be to look at how long they were employed there. I think the length of an employee’s employment is is important because the there’s a huge difference between having a job for 5, 10, 15 years then getting fired or working 3 weeks and being fired. Managers, coworkers and even jobs can change over the years and while you might have been able to do you job well in the beginning with the changes in technology for instance many jobs get harder because you have to learn new stuff to do the same job. Another question I would ask would be if why they were fired and if they have learn from said problem.
I had a coworker who worked with me at a local supermarket in the produce section who got fired because she only showed up for work about 40% of the time. She never called in or anything. If were giving her advice on how to get employed elsewhere the best bet would be emphasize that she was young, immature and bad at time management but, now she realizes the importance of being responsible.
