I’d already heard the Tuesday after payday thing before so many times and never really thought into why. Then I was thinking about how many more paychecks I’d get if I got laid off next Tuesday, and I realized why that must be the day… Because of the 1-week offset between the pay period and the paycheck week, if you’re 60 days starts Tuesday after payday then it ends exactly at the last business day of a pay period. Maybe that’s something everyone already knows, but I hadn’t seen it said here before. If you’re in a state with 90 day notice I think it works too because then last day of notice would technically be the Sunday after the end of a pay period, so no still no partial paychecks.
A takeaway here is someone displaced who doesn’t get a new job before notice ends will get 9 more paychecks after the day they get notice, plus an additional paycheck for each year tenure accrued beyond 4. Add 2 more paychecks to that formula if you’re in a 90 day state.
