A former baseball player was fired for racist tweet about mexicans his name was Mike Bacsik he was fired from his position on the team and also was suspended from the radio station that hired him but soon was canned from his position mike was fired from both his jobs on the radio and on the field immediacy played a role in this situation once the tweet was out he lost everything he had.
Immediacy once he made the post about mexicans it was there for the world there was no hiding it
Permanence the tweet was there everyone saw it all his followers saw his post
Lack of Control people can screenshot it and send it to everyone thats what happen with mike his bosses got the tweet and he was fired
The advice I would give him is dont tweet something you dont want anyone to see be careful about what you post online
