A promotion or a transfer changes more than your job title. The roster changes, the people change, and often the site changes too. The first thirty days are when your hours quietly drift, because you are busy proving yourself and nobody is watching your numbers for you.
The fix is simple: take a clear snapshot of how you worked before, then compare every week after. Do not rely on memory. A month from now you will not remember where the extra hours went.
Before your last day in the old role, save four weeks of your own record: how many shifts, total hours, overtime, and shift allowance. That is your baseline.
It does not need to be perfect to the minute. It needs to be honest, because it is the reference you will use when the pay or the allowance looks wrong after the transfer. Plenty of people reach month three with nothing but memory, and memory is no help in a conversation with payroll.
In the first month your pattern usually shifts in three ways: more shifts because you are covering a shortage, longer shifts because handover takes you longer, and less rest between them.
Check whether the pattern holds after week two. Week one is an exception, with induction, training and new faces. If the extra hours continue past that, they are a pattern, not an exception, and your record should show it.
Do not assume anything works the way it did before. Ask, and put the answer in a message or an email, even when the question feels obvious.
One short message after the meeting is enough. Write down what you understood and ask for confirmation. That protects you two months later, and it keeps the argument about numbers instead of opinions.
The biggest trap is unofficial extra time. You are new, so you stay half an hour late every day to finish properly. Half an hour a day becomes ten hours a month, and none of it is recorded.
The second trap is covering a shortage. When the team is one person down, your offer to help starts to feel expected. Log it as overtime and get approval before, not after.
The third trap is comparing yourself to people who have been there for years. They know the rhythm. You are still building yours, so do not judge your energy from month one.
Once you know the traps, let the record do the work. Shiftat-E is built to log your shifts, your hours, and plan your leave in one place. During a transfer that record becomes your reference: what you actually worked, how much leave you have left, and where the roster and reality disagree.
Start on day one, not on the day of the first argument. Log your shifts, your hours, and plan your leave in Shiftat-E, then install it here: https://play.google.com/store/apps/details?id=com.q8dm.shiftate
