Crossing a picket line (in my humble opinion) is never a good thing to do. If management sees that , it only strengthens their resolve not to bargain in good faith. Not everyone agrees with unions but there's a reason for them, in theory they protect the interests of the workingman against unscrupulous labor practices. Almost ALL arbitration is found in favor of unions when the facts are presented so that should tell you something. I was a steward in a union for almost 10 years so I've heard all the bullshit before about cost effectiveness, budgets, etc....but never ONCE saw management concede any of their pay raises or benefits to alleviate the issues. When you see those people out there tomorrow try and put yourself in their position, strikes are as a rule the last option they have.
