On February 4, Amazon workers at a Bessemer, Ala. facility will vote for a second time on whether they should form a union. Workers there voted against unionizing last February but the National Labor Relations Board found Amazon had “interfered with the employees’ exercise of a free and reasoned choice” and ordered a new election.

The effort is part of an increase in union activity in recent years. Last year marked a three-year peak in elections deciding whether workforces would organize for collective bargaining.

It was also the most number of active strikes in the US since 2006, according to new data from the Bureau of Labor Statistics (BLS).

The average monthly number of active strikes of least 1,000 workers rose to 2.75 in 2021. It’s the latest in an eight-year upward trend in strike activity.

While strikes and unionization efforts are rising, the national percentage of workers in a union has declined for 14 of the last 15 years. About 10.3% of all workers are in a union as of 2021.

Unions have won about 70% of unionization elections since 2012.

How many unionization elections were held in 2021?

The number of elections held to unionize workplaces increased in 2021. According to the National Labor Relations Board, 951 representation elections were held in 2021, a 12.8% increase from 2019.

Despite this, unionization elections are still lower than the 10-year average of 1,224.

Unions won about 70% of these elections last year, on par with the 10-year average. In addition to unionization elections, employers may choose to voluntarily recognize a union when at least 50% of employees in a workforce ask for representation. The government doesn’t keep data on voluntary union recognition.

Strike activity reached 15-year highs in 2021.
