You may have if you’re a salaried employee whose paycheck is based on a pro-rata basis of your annual salary. According to Daniel Schwartz at the
Connecticut Employment Law Blog, since these types of employees get paid an annual amount based on a 365 day year, regardless of the time they work each week, their paychecks probably didn’t reflect the extra day of work they put in on February 29th. Schwartz points out that employees paid on a bi-weekly basis will eventually make up the extra pay at some point, but there could be more of an impact for those paid on a monthly or semi-monthly basis.
