Review the change after four full weeks, against the pay stub rather than the memory. The numbers exist: the DOL's recordkeeping fact sheet requires your employer to keep hours worked each day and total hours worked each workweek for every nonexempt employee, to preserve payroll records at least three years, and to keep the time cards behind them two years. The condition that changes what you find: if the new schedule pushed you under 40 hours in a week, what you lost is overtime, and overtime is paid at a higher rate than the hours you kept.
Three columns: hours, dollars, handoffs
Hours is the easy column. Write scheduled hours, paid hours and hours away from home, including travel, for each of the four weeks.
Dollars is the column people skip. The CFPB's spending tracker asks you to track a full month rather than a week or two, sort receipts into categories, and write each category's weekly amounts into a category totals column; the categories that move with a schedule change are eating out, education and childcare, and anything travel-related. That tracker also tells you to circle the items that are the same every month, such as rent, car or cell phone payments, and those circled lines are exactly the ones a schedule change does not touch, so they stay out of the comparison.
Handoffs is a count, not a feeling: how many times someone else had to cover a pickup, a shift end or a delivery. Four weeks is the shortest window that produces a usable count, because one covered pickup in four weeks is a favor and four is an arrangement nobody agreed to.
Check your log against what the employer has to keep
Your log and the pay stub should agree on total hours for each workweek. When they do not, you have a specific question with a date on it rather than a general complaint. That recordkeeping fact sheet lists what the record must contain, including the time and day of week when the employee's workweek begins, the regular hourly pay rate, total daily or weekly straight-time earnings, and total overtime earnings for the workweek. Ask for the week that disagrees, by date.
If the change moved hours past 40 in some weeks, price them at the right rate. Overtime is due for hours worked in excess of 40 in a workweek at not less than time and one-half the regular rate.
Example: a 4 pm Tuesday finish, four weeks in
The old schedule ran 42 hours a week at $22.00 an hour: 40 x $22.00 = $880.00, plus 2 overtime hours at $33.00 = $66.00, for $946.00 a week. The new one finishes at 4 pm on Tuesdays and Thursdays and runs 38 hours: 38 x $22.00 = $836.00. The difference is $110.00 a week, $440.00 over four weeks.
The change removed the second trip on those two days: 11 miles round trip, twice a week, four weeks, is 88 miles. At the IRS business standard mileage rate of 76 cents a mile for July 1 to December 31, 2026, that is $66.88 back. Net cost of the trade-off: $373.12 over four weeks, or $93.28 a week, plus two fewer handoffs. The question is now answerable, and it is a money question: is the 4 pm finish worth $93.28 a week.
Notice where the loss actually sits. Only $44.00 of the $110.00 weekly difference is base pay; $66.00 of it is the two overtime hours that no longer exist. A change that removes overtime costs half again as much per hour as a change that removes ordinary hours, which is why the answer can be yes at 38 hours and no at 42.
Name one change and one date
End the review with a single line you can send: "The 4 pm Tuesday and Thursday finish costs me about $93 a week in hours. Can we keep the 4 pm finish on Tuesday and go back to the later finish on Thursday, starting the week of the 12th?" One change, one date, one figure. Keep the week-by-week entries in a factual scheduling log, put the next version of the request in a specific hours ask, and price any offered extra shift with the costs it creates.
