Overqualification - the condition of employees who believe that their qualifications exceed the requirements of their jobs - has been widely considered harmful for organisations, which is why most companies tend to screen out such job applicants.
Researchers at University of Notre Dame and Portland State University spent six months conducting interviews and studies of 11 information technology companies in China.
"When individual employees feel that they are not the only 'big fish in the pond,' and when overqualification becomes a norm rather than exception within the group, they tend to have more favourable reactions toward their own overqualification status and perform better," researchers said.
"Furthermore, organisations should celebrate employees' qualifications when they are first brought on board and point out how these overqualified employees are in good company by highlighting that they will be working with a highly qualified group," said Hu.
"Managers could also encourage more interactions among members to build team spirit, emphasising the importance of benefiting others through one's work, and highlight the interpersonal compatibility within a group to promote the positive influence of overqualification on employee attitudes and behaviours," she said.
