No, a performance improvement plan (PIP) is not legally required before termination in most US jurisdictions.
Under at-will employment (this is, 49 states plus DC), employers can terminate for any lawful reason with or without a PIP. The exceptions are Montana, unionized workplaces, and UK and EU jurisdictions, where documented warnings or fair-process requirements typically apply.
When a PIP or equivalent is typically required
In Montana, the Montana WDEA requires good cause to terminate after the probationary period, which defaults to 12 months.
On the other hand, across the US, most collective bargaining agreements call for progressive discipline, and terminations that skip steps are often overturned by arbitrators, in Montana and elsewhere.
In the UK, the ACAS Code of Practice recommends at least two documented warnings before dismissal for poor performance, and compensation awards can rise by up to 25% when the code is not followed. Germany needs a social justification and consultation with the works council. France needs a formal interview before dismissal, and the Netherlands needs a UWV permit.
Scenarios in which the Montana rules apply
- If the employee is working in Montana: (even if they are a remote worker for a company based in New York or Florida), the WDEA applies to them.
- If the company is in Montana: It must follow these rules for its local staff.
Why employers typically use a PIP anyway
A PIP creates the record that defends the termination when it is challenged. In EEOC investigations, it shows a legitimate, non-discriminatory reason and supports the employer in unemployment insurance claims. Skipping a PIP when the employee handbook promises one carries a breach-of-policy risk, and courts sometimes hold employers to their own written rules even in at-will states.
What a defensible PIP includes
- Specific, documented performance issues, not general complaints about attitude
- Measurable improvement targets with specific numbers
- A reasonable timeline, typically 30 to 90 days
- Support provided: training, mentoring, reduced workload, or extra check-ins
- A weekly or biweekly documented review schedule
- An explicit statement that missing targets may result in termination
Unrealistic targets or very short timelines read as "set up to fail" and can support a pretext claim in a discrimination case. Teams considering non-punitive options sometimes review alternatives to PIPs before starting one.

TL;DR
- A PIP is not legally required in 49 US states plus DC. Montana, union contracts, and UK and EU rules typically require a documented process.
- Employers commonly run a PIP anyway because it creates the defense against claims like wrongful termination, discrimination, and unemployment insurance.
- A defensible PIP has specific performance issues, measurable targets, a reasonable timeline, documented support, and explicit consequences for missing targets.
