In the United States the standard for paying one's employees, is not mandated by Federal law, but is left up to State law, though incredibly there are a few States, that don’t even mandate how often an employee must be paid, whatsoever. In most cases, employees are paid weekly, bi-weekly, semi-monthly, or monthly, of which, quite obviously few employees would ever prefer to be paid just monthly, and many employees would prefer the frequency of getting paid weekly. We read in Holy Scripture, "… The wages of a hired servant shall not remain with you all night until the morning" (Leviticus 19: 13), signifying that employees of that day and age, received their wages upon the completion of their work, each and every day.
No doubt, never has it been easier to create, process, and to issue paychecks to employees than it is today, in which, in many cases, a lot of employees no longer receive a physical paycheck but instead have their funds deposited directly into their banking account or even onto their smart phone. So that, changing the frequency of the pay period for employees is hardly a daunting task, which is quite relevant, since as reported by forbes.com, an incredible "78% of workers live paycheck to paycheck." This so signifies that employees that are struggling, which typically includes those that are making less than a living wage, should at a minimum, be paid weekly, and in fact, one could make a strong argument, that rather than their wages always being in arrears, that they should be prepaid each week, for their anticipated hours of that week to be labored. After all, when employees are paid their wages, they are essentially being paid for work done earlier in the month, or earlier in the semi-monthly pay period, or earlier in the bi-weekly pay period, or earlier in the weekly pay period, so that, in short, employees are giving to their employers, an interest-free loan which is being involuntarily provided from each one of them in aggregate. It hardly seems fair for employers to do such, for many an employer has gone belly-up or disappeared, with the employee wages in their hands, making the employees suffer for it. In point of fact, paying employees for a day's work, at the end of the workday, is about as fair as can be and there isn't any valid reason why employers should be able to hold onto their employee's wages for up to a month.
Basically, employees should receive their wages in a timely and current manner, and those employees that are making less than a living wage, obviously have a real need to get their hands onto the money that they have rightly earned, sooner as compared to later, of which, a weekly paycheck would permit these employees a better means to take care of their bills and creditors of all sorts, rather than pay periods of an even lengthier period of time. After all, if employers really valued their employees, they would make it their point to do more to accommodate them and thereby to pay them more frequently, for the money that their employees have earned, is theirs, and those that have earned that money have a right to it, which should never involve waiting periods of more than one week.
