May I ask why the current vacancies do not show hours and salary for the them?
Like many people I am sure, regardless of whether anyone applies for any type of employment, surely that information should be in the job description as then people are able to take into account various costs etc as to whether it is viable for them so as to enable them to give to the best of their ability all that is required for the role.
This is purely feedback for yourselves and you are not the only people/company to do this and, on a personal note, is something that should be addressed.
If you are therefore able to add this to the vacancies that you are showing, I am sure that your enquiries will increase which would then allow you to get an even better quality candidate for those posts.
I look forward to any response you may wish to send.
