☛ Since I was laid off from my previous employer, I have been actively looking for a job. However, as you know, there are many people looking for work and applying for the same jobs. I have always worked steadily but I haven't been able to find a job in the present job market.

☛ After I got laid off from my previous employer, I decided to go back to school to upgrade my skills so I can get a better, more secure job.
