Based on your profession and work needs, Although this is a mid shaft fibula fracture, if you conserve it (plaster) less changes of someone reducing it are there. You may end with a bony deformity , although it might not appear clinically. Minimum plaster is 4-6 weeks. Sometimes docs don't even advice plaster etc for this. Even in that scenario, reducing it is almost impossible as the big bone(tibia is intact) .

As it is only fibula fracture u can manage it conservatively , just take bed rest for few wks

It will unite in 6-8 weeks .
