I have been paid weekly for my last two jobs. When changing it was more work out (average) weekly pay rate and budget weekly. One job I was offered was slightly higher rate than the other but transport for the week would have been more expensive, so not worth it.
If you are paid weekly and work variable hours, do you think about your pay (and specifically how competitive it is) in hourly rate or the equivalent annual salary?
For example - would you look at another role and think, "that roles paying £8.90 per hour and I'm on £8.70, that's a good increase" or would you look at what your hourly rate translates to annually and then compare?
