Technician need to pickup the ticket mandatorily

Hi,
 
In our setup we have observed that before pickingup the ticket the technicians are changing the ticket status to in pending or resolving.Can we make the pickup option as mandatory so that we can make sure that no ticket will be closed as unassigned.
 
Please provide us a solution ASAP.
 
 
Thanks & Regards
