A warning letter documents a problem, explains the standard that applies, and gives the recipient a fair opportunity to correct the issue. Strong warning letters are factual rather than emotional: they identify what happened, cite the relevant rule or expectation, describe the improvement required, and explain what may happen if the problem continues.
The 20 examples below cover workplace, rental, school, customer, vendor, payment, safety, and conduct situations. Adapt the wording to your actual policy, agreement, and local requirements, and avoid stating consequences that you are not authorized or prepared to apply.
