The law does not permit employees to sue their bosses individually unless the boss has committed unlawful harassment. This one unfortunately circumstance would likely not qualify as unlawful harassment. Therefore it is very improbable that you could sue your boss and succeed.
I am not sure what you expect could occur, especially if you fear losing your job. The better course is to not show up late again and do what you can to rebuild a trust with your boss, not go to war with him.
Good luck to you.

I don't believe you have an action against your boss for "wrongfully putting you through a termination process." Perhaps you should talk to your union representation about the fact that you are working and not being paid.
