Can I send a message or paper letter for a negotiation?

No. All online offers should be negotiated using the online process.

Attachments can now be added at the offer stage for specific work items.

Where the attachment does not relate to a specific work item you should submit your negotiation to SLAB prior to attaching such a document.

To attach you then click on the click paper clip icon. You should NOT attach such documents before submitting your negotiation to SLAB.
