Administrators can now choose whether a line for the worker's signature is added to the certificates and wallet cards when they print. In the administrator portal, go to 'Monitoring', then 'Components' in the menu. Click on 'Safety Awareness Training'; this will bring up the settings for the component. The last setting at the bottom of the list is new:

The default setting is 'No', meaning that unless the user is printing a TDG certificate, there will only be a spot for the employer's signature. This is generally more convenient since the worker or an administrator can reproduce the signed certificate at any time from within the system (assuming the employer's signature has been uploaded). If you choose to add a spot for the worker's signature, reproducing the certificate would mean having to get the certificate in the hands of the worker, then filing away a signed copy (which can be made easier with our certificate tracking module).
Regardless of the setting, a spot for the worker's signature will always be added to Transportation of Dangerous Goods certificates. This is simply because this requirement is clearly stated in the TDG regulations.
