My current employer has financial difficulties. It has layoff 25% of the employees. I started to look for another job. I am expecting to be part of the next layoff.
Ouch, that really sucks. What kind of industry do you work in? 
I am working in IT but the job market is not good now. It is better to anticipate.
Ah, I can see why that would be stressful/upsetting. Well, it is good to plan ahead, but don't stress about it too much until you know for certain you are part of that 25%, the odds are still in your favour.
