The director of the Ryan White grant program in Nashville is on leave amid allegations of bullying, reports The Tennessean.

The Ryan White Part A program awards about $4.5 million in federal funds that help local people living with HIV/AIDS. The Nashville program is run by the Metro Public Health Department.

The Metro Government of Nashville put the HIV program director, Pam Sylakowski, on paid leave as it undertakes a human resources investigation into the program.

The Tennessean reports that four of five employees have left the program, allegedly because of bullying, which has left the vital program in disarray.

“We want to know how this program is being managed from a personnel—and a personality standpoint—now,” said Les Bowron, Metro Health human resources director, during a Board of Health meeting, according to the newspaper.

Sylakowski is expected to be on leave through much of next month.

This isn’t the first HIV-related controversy Sylakowski and the HIV program have faced. Last month, a computer database of clients’ personal information was left on an unprotected computer server accessible to the entire staff (more than 500 employees) of the Nashville Metro Public Health Department.

The current investigation is reported to focus on the human resources aspect of the program’s problems, not the data breach.
