Figure B
The prevalence of unfair labor practice (ULP) charges in union elections varies by the size of the bargaining unit: Share of completed union elections with a ULP charge against the employer, by size of potential bargaining unit, for completed elections for which a petition was filed or the election was completed in 2016–2017
| Bargaining unit size | Share of elections |
|---|---|
| 10 or fewer employees | 35.5% |
| 11–25 employees | 36.4% |
| 26–60 employees | 44.3% |
| 61+ employees | 54.4% |
Notes: ULP charges are charges that an employer violated the terms of the National Labor Relations Act (Section 8(a) of the labor code) by interfering with workers’ rights to form a union and bargain collectively. Data by bargaining unit size are available for only for those elections that were completed by the time we obtained the data in 2018.
