Alexander Bartokoff is a licensed paralegal who has agreed to supervise Melanie Wilson during her four-week placement at his firm. Melanie misses two days of her placement due to illness, but at the end of the four-week period Melanie presents her supervisor with dockets for those two days. Melanie tells Alexander that on those days and while she was ill, she worked at home, conducting legal research in order to prepare a research memo. Alexander Bartokoff refuses to sign dockets for those days because she was not in the office, and he had not instructed her to work from home. He is expecting Melanie to make up the two missed days at the end of her placement, but Melanie wants to attend convocation with her classmates. Returning to placement for two days will require Melanie to wait another three months until the next convocation is held, and her grandmother is flying in from England to attend the ceremony. Without those dockets, Melanie has completed only 118 hours of field placement work. Melanie does not understand why Alexander won't just sign the dockets. Explain his refusal. How many additional hours does Melanie need to complete to satisfy the LSO's field placement requirement?
