I will copy this post in UPS parcel forum.

UPS blindsided drivers this week by unilaterally imposing a new 70-hour work week through January 14.

Management created the new 70-hour nightmare by changing its method of calculating Hours of Service to 70-hours-in-8-days, without any negotiations with the union.

The company’s actions are unfair and unsafe. Our International Union can stop UPS. Here’s how.

Step One: Demand Bargaining and File an Unfair Labor Practice Charge
By law and by contract it is illegal for UPS to unilaterally make this change without bargaining with the union first.

The Hoffa administration should immediately demand that UPS bargain over the issue, and file a national grievance and an Unfair Labor Practice charge with the National Labor Relations Board.

Step Two: Tell UPS that the IBT Does Not Recognize the 34-Hour Restart Rule in Package
UPS changed to a 70-hours-in-8-days Hours of Service calculation to be able to force some drivers to work a sixth punch, and to force package drivers to work up to 70 hours a week.
