So I've been applying for new jobs lately and I've noticed a lot of places ask for current or previous salary details on their application forms. I'm leaving this blank wherever possible (I am applying for jobs on a similar level to my current position so not trying to move up). I don't understand how this information would be constructively used by a potential employer, other than to offer a potentially lower salary than they had originally planned. Wondering if I'm paranoid or can this info actually be beneficial for both prospective employer and employer
As far as I’m aware, it’s usually so they can salary match, as oppose to offering a potential lower salary. You can also salary negotiate should their offer not meet your requirements.
In addition to Andriana's point, it's a way of assessing greater meaning behind a person's employment history.
"Project Officer" roles, by way of just one example, could mean a huge range of things and I know of Project Officers on £21k and Project Officers on £75k and their roles, skills and qualifications are, naturally, very different.
So seeing the number associated with the job gives the recruiter an idea of whether the applicant is a suitable match.
Is it accurate? No. But it is a potentially helpful additional data point.
Just another note depending on the size of the company your employer can see your previous salary ballpark from HMRC so it's also not worth lying about either.
