Final answer:
A cooling-off period requires workers to return to work during a disruptive union strike, providing time for negotiation. Additionally, a probationary period is a trial phase for new employees, where dismissal without cause is permissible.
Step-by-step explanation:
During a cooling-off period, which is declared in the case of a disruptive union strike, workers are required to return to work despite ongoing labor disputes. This measure is intended to prevent harm to the public interest and provide time for negotiation between the union and the employer.
Similarly, in employment practices, a probationary period is often set to evaluate a new employee's performance, during which time an employer can terminate the worker without cause and sometimes at a lower rate of pay.
