Remember that we represent all members. Try to exhaust each step before advancing to the next. Timelines can be extended but should always be in writing. If the boss is unreasonably delaying the process, you might want to make a strategic decision to move on and refuse to extend timelines further. Union should not be responsible for delaying the process.
Members complain about the process taking so long.
We are also guilty of delays. The best way to avoid this is to prepare early. Use your checklist and build your file. Don't wait for the last minute and then realize you did not request the information you needed to prepare your case. Actively enforce the contract.
