@OP. Ratings, hard work and meeting deadlines do not matter anymore. Layoffs in the last 5 years showed no distinction among those that achieved TA and the low performers. Totally "arbitrary" layoffs if you look only at performance. Just add age and pension, and a pattern emerges. Some people were "randomly" picked up to mask the ageism in the layoffs. Therefore, I'd not worry too much (just a little) about the inconsistent (how/what) since managers were forced to give those.
The !diots at the helm haven't changed, so why things would change at FMC? People should realize that they have no control over who's getting the boot, so they should take it easy. Inconsistent or not, we are all in the same sinking boat. The ones closer to retirement should be the main target of layoffs, plus some young "kids" to balance the average age and avoid lawsuits.
All Ford FTE and Agency should have money saved for the storm brewing. They should be looking for another job, particularly the younger crowd. The job market is not great, but there are some openings (with a lot of competitors). I agree about brushing up the resume, updating some skills, and start looking for a new job. Remember you can always say no, if the offer is too low.
In my case, I guess like many of my age here, is harder to get picked by another company. Plus the salary I have at Ford is better than most job openings. OP, you say 3 years before bankruptcy? I am fine with that. But I am sure my case is not common, so I still advise people to check the finances, and cut expenses.
Good Luck!
