What controls will exist when requesting contingent help? Can anyone submit a contingent worker request?

Harvard schools and departments (tubs) will authorize specific hiring managers to use Fieldglass to requisition contingent workers -- initially, and on an ongoing basis through HR authorized requestors. Hiring managers are assumed to have the authority to hire a contingent worker with an estimated cost below $10K.  For a contingent worker assignment with a cost >$10K, additional financial approvals are required.
