Will Schuester (Matthew Morrison) is the director of the glee club at William McKinley High. He was teaching Spanish when the former director was fired for inappropriate conduct. Previously a glee club member in his own high school days, he decides to give new life to the group. His love of music helps bring the kids together and overcome many of life's obstacles.
The glee club must have at least twelve members to compete in sectionals, which will ensure that they keep their funding. Getting those twelve members is tough, when the whole school thinks glee club is the geekiest thing since the AV Club. So, Will is always trying to recruit new members and solve disputes to keep from losing existing members. There are many issues within the group including a pregnancy, members who struggle with their sexual orientations, bullying, body and confidence issues, infiltration by spies and general teenage angst.
Will is constantly dealing with his own set of issues as well. One of these struggles includes a strong rivalry between him and Sue Sylvester (Jane Lynch), the cheerleading coach. They are competing for funding and Will must convince Principal Figgins (Iqbal Theba) that the glee club is worth funding. Sue goes to whatever means she deems necessary to sabotage Will and the group. She sends her Cheerios to join the club and report back to her, convinces glee club members to quit and join her team, makes outrageous and often untrue claims and does crazy things like stealing their Christmas tree.
If his problems at work weren't enough William is also struggling through a divorce from his wife Terri (Jessalyn Gilsig) which has caused him immeasurable pain. Despite knowing about his love of teaching, she tried to force him to get another job that pays more, dismissed his passion for the glee club and to top it all off even pretended to be pregnant. Throughout all of this Will discovers himself falling in love with Emma (Jayma Mays), the school guidance counselor.
In the second season Will befriends the new gym teacher known as "the beast" (Dot-Marie Jones). At first he joined up against her with Sue, in fear of losing money to a football team that is finally winning. But quickly realizes that by doing so, he is just as bad as Sue and apologizes. They begin working together to inspire and teach the students.
Emma begins dating her dentist and can no longer entertain Will's advances after he cheats on her with a rival glee club director. Will still loves her and makes ridiculous attempts to win her heart back from Carl (John Stamos) who is willing to take their relationship at her pace in order to help her get over her fear of germs.
Overall, though Will is far from perfect, he proves time and time again that he is a dedicated teacher who cares deeply about his students. He is always willing to listen to their problems and is frequently the mediator of whatever fights have broken out among them. Even if he occasionally lets his desires and competitiveness get the better of him, such as when he tried to have the glee club put on the Rocky Horror Picture Show in order to impress Emma, Will always comes to his senses and does the right thing.
