It's raising eyebrows at City Hall for a number of reasons, partly because Weis himself made a policy change in 2010 that allowed command staff members to carry up to 39 unused vacation days from one year to the next.
Weis resigned from his $310,000-a-year job on March 1.
Weis told the Chicago Sun-Times that it is city policy to compensate employees for vacation time earned but not used and that his specific payment was vetted by the police department and others.
