Paying weekly is a big expense for an employer.
If you receive a pay check every week or every other week you receive the same total amount. Your only problem is the first pay day that takes effect on the 2 week schedule. After that the only problem would be your budgeting skills.
If you work as a 1099 contract worker you can get paid weekly.
why does it matter - a biweekly check pays 2 weeks worth of pay
