Also worth noting that most companies prefer to treat any given firing as “without cause” because stating a reason is usually a net-loss in terms of legal exposure.
Exceptions to the rule include, but are not limited to:
States which make it expensive/slow to fire without cause (because money)
Union jobs (because union)
Retaliative firings (because worker’s rights)
Prejudiced firings (because civil rights)
How does one tell if they’re on the road to a with-cause termination? Simple: documentation. If you’re suddenly being put under a microscope it might indicate that a premeditated f-bomb is hiding around the corner.
