Nope, never seen it done "on the spot". Every time it's happened around here there has been a meeting with the shop steward, usually first thing the following morning unless there happens to be a shop steward standing around at the time.
Typical scenario-
Sup: Do this
Employee: No
Sup: Are you refusing to work as instructed?
Employee: Yes
Sup: We'll talk about this tomorrow morning. Don't plan on working.
In that case the sup should be fired for failing to do his job. I'm not a big discipline nut but you can't run an operation if you let people decide what they will and won't do.
