Verb. Operational Cockblocking: the act of getting ahead in the workplace rejecting your idea, but as their means to get ahead later in the future. See Operational Clockblock.
But today an Operational Cockblock happened to me.
Where my boss rejected an idea I had, because they thought it was dumb; although the idea would have saved the company millions.
Where a year later........:
Your boss got promoted because they used your idea they "brilliantly suggested"....
......and a week later: you get fired.
