The growing number of lockouts—where employers close the doors or gates in order to wring concessions out of workers—“represents an overreach on the part of employers,” writes Minnesota AFL-CIO President Shar Knutson, in an op-ed piece today in the Minneapolis StarTribune.

For examples of these lockouts, Knutson points to the more than 13-month lockout of American Crystal Sugar workers, the NFL lockouts of referees and players, Cooper Tires recent lockout and this month’s lockout of the Minnesota Orchestra (American Federation of Musicians of the United States and Canada [AFM] Local 30-73), where management is seeking 30% to 50% pay cuts.

Pittsburgh Steelers partisan and union radio guy Charles Showalter is happy the union refs are back on the field.

But Showalter thinks unions should use the lockout as a teaching moment. So does Bill Londrigan, president of the Kentucky State AFL-CIO. Says Showalter, host of “The Union Edge: Labor’s Talk Radio” show:

The NFL’s lockout of its veteran and trained professional corps of referees is now over after the league and the NFL Referees Association (NFLRA) reached a tentative eight-year agreement late Wednesday night. The referees will hold a ratification vote Friday and Saturday. AFL-CIO President Richard Trumka said the end of the lockout means:

A football season, which started in disaster, can now get back on track. Not only toward fairness and integrity for the game, but ensuring the highest level of safety possible for the athletes who play the game.

The NFL referee lockout is a complete disaster—something that’s obvious to everyone except (supposedly) the people keeping the referees locked out. Much ink has been spent on decrying the replacement referees and how they’re ruining football (never mind how they’re putting players’ safety at risk). What hasn’t gotten much attention in this lockout is symbolic of a much bigger issue: Training for a high-performing workforce matters.

The union movement is the largest workforce trainer of adults outside the U.S. military.

If you were building a bridge, would you hire a work crew with a few hours of metal shop on their résumés, or trained and certified Ironworkers? Would you go into surgery with someone who only has a CPR certificate, or a real doctor with a medical degree?

If you’re NFL Commissioner Roger Goodell, or one of the 32 NFL team owners, you'd go with the newbie—at least it seems that way, given their decision to lock out professional NFL officials and instead use untrained, unprepared and in-over-their-heads replacement referees.

Any fan of the NFL who has watched the season unfold with replacement officials because the league has locked out the skilled and veteran officials knows calls are being missed or called incorrectly and the replacements have a tenuous control of each game. But even worse, say the players, their safety is at stake.

In a letter to team owners urging an end to the lockout of the referees, the Executive Committee of the NFL Players Association writes:

A little more than year after locking out players, the National Football League (NFL) is now locking out its referees and is recruiting replacement officials. In a statement, the NFL Players Association (NFLPA) says the lockout, and possible use of replacement refs, threatens player safety.

In 2011, the NFL tasked officials with increased responsibilities in protecting player health and safety, and its search for scabs undermines that important function. Professional athletes require professional referees, and we believe in the NFL Referees Association’s trained first responders.
