Within four to six days, you should have your letter of authority ready. The process could take longer if there are any issues with the application or if it needs to be reviewed by a supervisor. It is not unusual for letters of authority to take several weeks to months to arrive. The length of time depends on how quickly your employer can get back to you. If they need more information from you before they can issue the letter, then they will ask for that information up front. Otherwise, they can usually send the letter out once they have all the necessary details. Your employer may also have other duties and responsibilities that don't show up on your paperwork but which are still important to your case's progress. For example: answering questions about your job, reviewing your work records, giving you training on the job. These are all part of what is called "internal union procedures" and since they aren't shown as tasks on your form, they can delay your letter of authorization. However, even with these extra steps, it is only normal for letters of authority to take four to six days to be sent out.
