CHATTANOOGA, Tennessee, April 19 (Reuters) - The United

Auto Workers is counting on scoring a seismic victory at

Volkswagen's Tennessee plant as unionization votes

are tallied on Friday - one that opens up the anti-union U.S.

South to organized labor.

A win would make the Chattanooga factory the first auto

plant in the South to unionize via election since the 1940s and

the first foreign-owned auto plant in the South to do so.

It would also be a huge shot in the arm for UAW President

Shawn Fain's campaign to unionize plants owned by more than a

dozen automakers across the U.S., including Tesla. Fain

and his team have committed to spending $40 million through 2026

on the effort.

Federal officials from the National Labor Relations Board on

Friday evening will start the counting of ballots after three

days of voting ends, with results expected around 11 p.m.

Eastern Time (0300 GMT).

"Everybody else is watching," said Isaac Meadows, a worker

at the VW plant, who said he voted in support of the union.

"This is going to change the labor landscape across the

country."

Although the UAW narrowly lost votes at the same plant in

2014 and 2019, this year's vote has been preceded by surging

public support for unions and successful contract negotiations

last year with the Big Three automakers.

The UAW has said it sets votes in motion once 70% of

eligible workers at a plant - of which there are approximately

4,300 at VW's Tennessee factory - have signed cards supporting

unionization.

While success for the UAW is widely expected to bolster

unionizing momentum at other factories, anti-union sentiment is

entrenched in many parts of the U.S. South. Earlier this week,

Republican governors in six southern states including Tennessee

spoke out in opposition to the union drive.

"We're going through an unusual, even unprecedented period

when it comes to unions more generally and VW is at the

epicenter of that right now," said Harley Shaiken, labor

professor at the University of California, Berkeley.

Over the last several months, a group of volunteer workers

at the plant, which produces the electric ID.4 SUV and other

vehicles, held organizing meetings to drum up support, with

occasional guidance and assistance from Detroit's UAW officials.

Some of the plant's employees have countered that joining

the UAW could weaken workers' job security in the future.

Workers on both sides agree that the plant's campus has been

quieter than previous years as ballots were cast, contrasting to

past votes when scores of union supporters and opponents - both

employees and members of the wider community - lined the

driveway.

VW has said it has taken a neutral position on the vote at

its only non-union factory globally. The UAW has previously

represented VW workers at a Pennsylvania plant that built Rabbit

cars before it closed in 1988.

For decades, the union has struck out at southern auto

plants. In addition to the two narrow losses at VW previously,

it sustained three more significant misses at southern factories

owned by Nissan ( NSANF ), the last in 2017 in Mississippi.

The broader labor movement has since gone through somewhat

of a renaissance, with a record number of workers across various

industries going on strike last year.

Last autumn U.S. President Joe Biden walked picket lines

outside Detroit, where the union scored double-digit percentage

raises as well as cost-of-living increases from General Motors ( GM )

, Ford Motor ( F ) and Stellantis ( STLA ). That sparked

a wave of hikes by non-union automakers that some analysts said

were designed to keep out unions.

A Mercedes plant in Alabama, at which a majority

of workers have signed cards indicating they support

unionization, will be the next facility to hold a UAW election,

the week of May 13.

The UAW has also said that more than 30% of employees at a

Hyundai plant in Alabama and at a Missouri Toyota

auto parts factory have signed cards indicating they

want to join the UAW.
