Do you think moonlighting should be prohibited?

Employers are free to implement their own policies on employee moonlighting as there is no law that prohibits employees from simultaneously working for more than one company. Moonlighting policy is important because of following reasons:

a. Because of simultaneous jobs an employee may not be able to perform well in his/her primary job.

b. Employee might use tools and technique of primary job while working for another company.

c. Employee may work for the competitors of primary employer, which may lead to leak of information.
