The months in Town Manager Michael Caira’s tenure are quickly winding down, and his replacement is hard at work preparing to make the switch as smooth of a transition as possible.

Included in the packet for the Board of Selectmen at Monday’s meeting was a letter from Assistant Town Manager Jeff Hull, who will take over as Town Manager this fall pending a successful contract negotiation. In the letter, Hull laid out the timeline for finding his own replacement.

According to Hull, the job of Assistant Town Manager was changed and re-titled as Assistant Town Manager/Human Resources Director. The town will send the job description to two professional municipal organizations and each will use the posting to seek qualified candidates.

In addition, the letter said, Hull provided notice to the Massachusetts Municipal Personnel Association (MMPA), which will notify members of the job at their meeting on July 19.

Once the town receives relevant resumes and applications, Hull said a committee with himself, designated department heads and Caira will conduct interviews with “a short list of candidates” in early to mid August.

“Assuming that the pool of qualified candidates is sufficient to draw upon an individual with the requisite mix of relevant experience, education and training then it should be possible to make a job offer by mid to late September,” said Hull. “Depending upon the successful candidates’ current employment circumstances and their requirement to provide sufficient notice to their employer, the position of assistant town manager/human resource director should be filled before the end of October at the latest.”

Addressing the transition to his new position, Hull said he asked department heads throughout town to provide him with a variety of information by month’s end. That list included priorities for the near future, personnel matters that may be affecting their department, and other pertinent information.

Hull told selectmen that a pair of part-time positions have been unfilled in recent years and that he will be meeting over the upcoming weeks with town personnel to formulate a job description to fill the part-time job.

“With the initial stages of the Fiscal Year 2014 budget preparation beginning in September, filling these positions in a timely manner is critical,” said Hull.
