Got let go after showing up late to mandatory retraining (I found out the day of, and we didn't have smartphones then), which resulted in moving to another company across town for a contract where conversion was a "sure thing" just to have the contract run out 3 months later and not get renewed. No official reason given for either, but I can read between the lines.
As I was still reacting to the news about the contract, the IRS seized my assets based on a clerical error on their part, resulting in an already tight financial situation turn into a nightmare. After being unable to find paying work for months, my vehicle was repossessed and I was evicted, broke with no support network.
Over the years since then, I've hustled to get back on track, but that one year's repercussions are still being felt today.
