How to work out pro-rata if hours not specified?

[cakedup]

The job is ad hoc and hours will depend on what's available and what kind of work you are willing to do. The rate of pay is £10-15k pro rata. Is there any way I could work out how much this is an hour?

You would need to know how many hours a full time employee does per week.

And even if you know how many hours fulltime is, £10-15K is a fairly large range so it won't be a huge help to you in working out how much you might get paid, particularly as the work is ad-hoc.

Ok thanks. It's this particular website that only allows jobs advertised to post salaries within certain brackets.

You're looking at nmw I'd say. The max would be £7.50 ph

I kind of figured that too Littlef00t but then the job description states "excellent rates of pay" so I thought it can't just be the nmw!
