union security agreement
A union security agreement is an agreement between a labor union and an employer that the employer will require all employees to undertake a specified level of support for the union as a condition of employment.
This level of support compels employees to become members of the labor union before a certain period of time, generally 30 days, has lapsed, as well as make certain payments or “agency fees” to the union and initiation fees as a condition of getting or keeping the job.
“Right-to-work” laws prohibit and invalidate union security agreements and union shops.
