If you have already booked your flight and your employer is refusing to grant your requested leave, it can be a difficult situation. However, before taking any legal actions, it is advisable to try resolving the issue directly with your employer. Communication is key in such situations. You can approach your boss once again and explain the importance of your planned vacation and the difficulty in canceling or rescheduling your flight. It might help to provide any necessary documentation or proof to support your request. If your employer still refuses to approve your leave, you can consider contacting the labor department for further advice and guidance. Employment laws vary by country, so it is essential to consult with the appropriate labor authority to understand your rights and the potential options available to you. They will be able to provide you with accurate information about your legal standing and the steps you can take to address the issue. Prior to reaching out to the labor department, gather all relevant documents including your confirmation letter explicitly stating a 14-day annual leave entitlement and any communication related to your leave request. This will help support your case and provide evidence of your efforts to resolve the matter internally. Remember, it is crucial to remain professional and polite throughout the process to maintain a positive relationship with your employer.
