Final answer:
Of the options provided, none explicitly outline a conventional disadvantage of biweekly payments. However, potential disadvantages may include the need for more careful budget planning due to the less frequent income on a biweekly schedule compared to weekly payments.
Step-by-step explanation:
The question focuses on identifying a potential disadvantage of being paid a salary on a biweekly basis. To answer this question, none of the provided options (1) The salary is not consistent throughout the year, (2) The salary is not paid on time, (3) The salary is not enough for her expenses, (4) The salary is not taxed properly, directly relate to being paid biweekly. However, discussing this broadly, a potential disadvantage of biweekly payment might be related to budgeting issues, as individuals may need to manage their expenses for longer periods without receiving income compared to weekly payments.
Outside of the provided options, some employees prefer getting paid more frequently to help manage their expenses, so one disadvantage could be that managing monthly expenses might require more planning when income is received less frequently. Also, there can be timing issues if their bills are due on a different schedule than their paychecks. It is worth noting that each of the options provided as possible disadvantages could be valid concerns, but they are not specifically tied to the frequency of being paid biweekly.
In the context given, issues like salary consistency, on-time payment, sufficiency of salary for expenses, and proper taxation are not typical disadvantages related exclusively to biweekly pay periods.
