Add current jobs to employees

As a request-savvy integrator
I want the employeeModel to include an array of current job IDs
So that I don't have to make additional calls to get that

In our use-case, we always need certain information about the current job(s) that an employee has. In order to use and present the data, we must make requests to obtain first the employee, then the jobs (filtering by employee ID and active). If the employee model included the job IDs, we would be able to significantly reduce our API calls, improving user experience and reducing server load.
