If a salaried employee worked *any* part of a day, he or she must be paid for the whole day--it's only if he or she did not work *at all* that day that the employer does not need to pay.If the salaried employee worked at all but was not paid for the whole day, he or she could contact the department of labor to file a wage and hour complaint, and/or file a lawsuit (e.g. in small claims court) for the money.
