I was recently hand-picked for a promotion to backfill my boss, but when HR came to give me the offer they told me my old pay grade was identical to the new one (yeah, I know, that's weird as hell). Anyway, they told me it would be a lateral move, BUT I would be moved into the management bonus structure which historically has been 8% quarterly. Once I accepted (yeah, I know, I'm looking at other options) they told me I didn't actually qualify for any bonus payout until April of 2026.
I've had bonuses in the past that were as low as $5, this is by far the worst and will be the reason I leave.
