San Francisco, March 1 (TIWN) US President Joe Biden has offered his support to unionisation efforts of workers, as employees of Amazon in an Alabama warehouse vote on whether to unionise.

While Biden did not mention Amazon, the reference was clear when he mentioned "workers in Alabama" in a video produced by the White House. He defended the workers' right to decide whether to form a union without intimidation by employers.  "Workers in Alabama -- and all across America - are voting on whether to organize a union in their workplace. It's a vitally important choice -- one that should be made without intimidation or threats by employers," the US President said in tweet introducing the video late on Sunday.
