Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek. 

I regularly hear from United Airlines Flight Attendants.

I rarely hear about how happy they are.

Something is amiss with the way they believe the airline is treating them. 

And now the Flight Attendants have had enough. 

The Association of Flight Attendants -- the United Flight Attendants' union -- has announced it's launching a Day of Action against the airline.

This time, it's personal.

The Flight Attendants have a long list of grievances that they say the airline has consistently ignored.

These include payroll issues, poor hotel accommodations and crew scheduling -- including the sneaky system I described a couple of weeks ago, which some Flight Attendants believe deliberately tries to get around giving them the legally mandated 10-hour rest period.

Worse, say the Flight Attendants, the airline is deliberately reducing staffing.

As my colleague Bill Murphy Jr. reported, United has given up on plating food in the air and simultaneously reduced the number of Flight Attendants on certain flights.

As part of their Day of Action, the Flight Attendants union has already made a mockery of United's Core4 logo.

Core4 was the airline's attempt at emphasizing the basics of customer service -- Safe, Caring, Efficient and Dependable.

The union's new version of the logo has the headline #CORED and depicts an apple that's been eaten away.

As if one hashtag isn't enough, there's also another: #Enough

I asked United for its view. A spokesperson told me: 

We will continue to work closely with the AFA on issues that are important to our flight attendants. We don't expect any impact on our customers.

The trouble with the unexpected is that it sometimes happens.

It's unclear what specific actions the union might want to take. But if you don't want to be confronted by, say, picketing, chan Flight Attendants, perhaps you should avoid flying United on December 13.

That's the day the union intends to make its voices heard.

Not all Flight Attendants are fully supportive of the union, however. I've heard from some Flight Attendants who believe the union is largely ineffective.

One told me: 

By taking the flight public, the union is admitting to and proving their incompetence. After all, what are Flight Attendants paying them for?

There's something, though, about big airlines that don't seem to do so well in the customer service area.

They also seem to be the ones with the worst labor relations.

Could these two things be connected?
