Workplace Rant....What to do?? Kinda Long...Sorry

Exactly as it should be.
Our industry does have a few slackers, now that i really think about it. The thing is that companies are NOT obligated to keep them working. Those individuals will be "sent back to the hall". And the dispatchers will send them to another company. (whichever company is asking for guys). Sometimes, however,especially if the industry is not busy, those individuals will end up on an unofficial no-hire list. (the company owners all know one another) and end up being "in the hall for a long time". The easiest ways to end up in this category is by being unreliable, (blowing shifts), or being a DOG F-ER. And I for one especially hate the fellas in the second category. But, as I said before, as union members, we can NOT be held accountable for other workers downfalls. So, each to his/her own perogative. i think we all hate lazy workers. By the way -20 temperatures seperate the men from the boys up here. (outdoor construction) EH !
