About a year ago I was separated from my job as an assembler due to a violation of the company smoking policy. Since then, I have been unable to find a suitable job. I am considering a career change because I found a job position online for a dental laboratory support technician that interests me and I am considering applying for it. My question is, now that I've been unemployed for a year, should I address this in my cover letter? I feel that I should explain the gap, but I don't have any real experience in between the time that I was fired and now. I have been constantly looking for a job, helping my mom who was diagnosed with COPD, and taking care of my kids but I feel there should be more substance. Please advise me on this. Thank you!
