A yellow dog contract is an agreement made between an employee and employer where the employee agrees not to join a union as a condition of employment. These contracts are legal in jurisdictions where right-to-work laws exist, but they are generally frowned upon by labor organizations and other advocates for worker rights.
In other words, once someone signs a yellow-dog contract, they are bound by their word not to join a union. Employers often use these contracts to prevent workers from organizing or bargaining collectively.
There are both advantages and disadvantages to such agreements. Some of the advantages include:
On the plus side, for employers, these agreements help prevent unions from being formed in their workplace. This can save the company money on union dues and help to keep relations between management and employees more cordial. Additionally, employers may require workers to sign yellow-dog contracts as a condition of employment. On the downside, yellow dog contracts can be used to discourage employees from joining or supporting a union. This can lead to workers feeling like they do not have a voice in the workplace and their rights are being violated.
