A more thorough explanation:

Definition: The last-straw doctrine is a rule in employment law that allows an employer to terminate an employee's contract if there is a series of incidents of poor performance, none of which alone would justify termination, followed by a final incident that shows a blatant disregard for the employer's interests.

Example: An employee has been warned several times about being late to work, missing deadlines, and not completing tasks to the required standard. However, the final straw is when the employee is caught stealing from the company. This final incident shows a blatant disregard for the employer's interests and justifies the termination of the employee's contract.

Explanation: The last-straw doctrine allows an employer to consider the entire history of an employee's performance when making a decision to terminate their contract. It recognizes that a single incident may not be enough to justify termination, but a pattern of poor performance followed by a final incident can be. In the example given, the employee's repeated poor performance was not enough to justify termination, but the final incident of theft was the last straw that led to the termination of their contract.
