I would drastically prefer a lack of warning over a lack of reason, and I cannot help but interpret any other position as disingenuous.

I suppose it depends if you value your own ego over your financial well being?

I don't hold any expectations from my employer other than being an employer. Being hired is as much part of a job as quitting or being fired.

All that said, I don't care what reason an employer has to wanting me out. It really does not matter to me. All I need is time to plan ahead so I come out unscathed. Who knows? I may even find a better job on my way out.

A lack of warning can leave you in the lurch financially and career-wise. Getting the heads+up that it's time to find a new job let's you keep banking paychecks while you make a seamless transition to a new opportunity.

>a lack of warning over a lack of reason

The choice is one or both...
