Late return of a company car is a legal reason for immediate termination of employment
If an employee (Sales Director) unjustifiably (in breach of an order to return) withholds the employer's property of significant value (company car) for a period of 17 days, the employee has committed a direct attack against the employer's property and has abused his position as an employee whose obligation was to use such property for work-related purposes. Whether the employee's intention was to create "a better negotiating position for further discussions on continuation of his employment" or only withheld the car or was using it for his personal purposes is irrelevant. This attack against the employer's property (though an isolated incident on the part of the employee) constitutes a reason for immediate termination of employment.
