I don't know that I've ever had monthly. Most of the time my pay has been twice a month or every two weeks (the latter ends up with some weird scenarios at some companies where there's no benefits deduction in a 3-paycheck month). I've had a handful of jobs that paid weekly. The worst was contracting somewhere where I did weekly timesheets but was paid bimonthly. It was just after another contract agency had shortchanged me on my pay so I had to keep a manual log to make sure that all the hours I worked were paid.
