Final answer:
Employers must typically cancel a work pass within a certain period after it has been revoked, with the timeframe varying by location. The option within 7 days may be correct for some jurisdictions like Singapore for certain types of passes, but this depends on the applicable legal context.
Step-by-step explanation:
When an employer has a worker's pass revoked, it's important for them to understand the regulations regarding the termination of the pass. Based on the options provided, employers are generally required to cancel a work pass within a certain timeframe after it has been revoked to comply with legal standards. However, the specific deadline can vary depending on the jurisdiction and the type of work pass.
While I cannot provide a definitive answer without knowing the specific legal context (e.g., country or type of work pass), often regulations require prompt action from the employer. If the scenario implies a standard set by Singapore's Ministry of Manpower for Employment Passes, for instance, the correct answer might be within 7 days of the pass being revoked or the employee's last day of work, whichever comes first.
It's important to consult the relevant government website or legal resources for the exact requirements in the given jurisdiction to explain and ensure the correct procedure is followed. If an employer does not terminate the work pass within the required period, there may be legal consequences.
