I apply for a vacation leave last month for the wedding of my sister. Submitted all the papers they asked including my plane ticket but i was informed that it was not approved. What should i do?
What should i do?
You should ask why it was not approved. Then your subsequent actions can be based on more than just a "no" decision.
If you think they don't understand how important the vacation is to you, you should explain it.
If you think they feel that they cannot get along without you, you can explain how they can.
If you think they are just being mean, you might be able to appeal to HR.
If you think they are doing something illegal, you should talk to your lawyer, or whatever is the equivalent of a Department of Labor or Attorney General for your locale.
If all else fails, you get to decide which is more important - this job or attending your sister's wedding.
You submitted all papers they asked for including your flight ticket ? Your company seriously asked you to provide flight tickets to get a holiday approved and then rejects it?
Either someone in that company is seriously in the wrong place, or they want to get rid of you. I'd assume the first. In order of things to do: You go to your direct manager and ask him or her straight if he has told HR to reject your holiday or not. That's a very important piece of information.
The possibilities are: He or she isn't aware of anything and doesn't mind you taking the holiday at all. Or he or she thinks they would be better of with you there, but isn't aware that it's your sister's wedding and your flight tickets are paid and can live without you. Or they are fully aware and don't give a damn about what you want. These bosses exist.
If HR disapproved your holiday, you go to them next, armed with that information from your manager. What you ask them to do depends on what your manager said. If it's HR's fault, you tell them that your manager approves your holiday, and you want the person who decided tell you in person their reasons. Thoughtless, uncaring decisions are much harder to make face to face. If it was your bosses fault, you go to HR and ask for your holiday and a transfer to a different part of the company.
In the end, if the company refuses your holiday with no good reason, you can start looking for a new job. Signing for a new job means you can take your holiday, no matter what the company says. If you are confident you'll find a new job, but would like to keep your job, you can say "I don't know whether I will go on this holiday or not, don't be surprised if I'm not there on Monday". That puts the decision into their hand.
