So you are agreeing with me, that those who do a crappy job cannot be fired because they are in a union.
You should have simply said so from the start.
So you're trolling in a deliberately obtuse way, right?
Generally speaking, individuals who are deemed to have committed an offense worthy of termination are immediately suspended w/o pay pending further investigation. Formal charges are then formulated, and the individual has the right to answer them w/ assistance from the Union. This usually occurs at 2 or 3 levels in meetings with management. If management insists on termination, that's what happens, and the Union may or may not demand arbitration, depending on the desires of the individual, the circumstances & a vote by members of the Local. Management & Union agree on a professional arbitrator, & a date is set for a hearing, often far in the future from the original offense. The arbitration process often lasts for a year or more, during which time the offender is terminated w/o pay.
Anybody who claims that it's impossible to get fired from a Union job is extremely ignorant or lying, take your pick.
Which has nothing to do with the subject at hand, and is just a duh-version into the well worn path of conservative pissing & moaning.
