The president of the Fraternal Order of Police Fort Pitt Lodge yesterday filed a federal lawsuit against the city of Pittsburgh, alleging that it is improperly calculating officers' overtime pay.

The claim asks that other similarly situated officers be allowed to join Officer Daniel O'Hara in his lawsuit.

According to the complaint, from 2006 to the present, the city has been paying police officers incorrectly for overtime - including in some cases, not providing longevity pay or an agreed upon 3 percent shift differential in its calculations.

The city faced a similar lawsuit in 2005, though that case was settled when it agreed to adjust its payments.

In the current complaint, Officer O'Hara said the city has agreed to do recalculations for all of 2009, but his claims date back to 2006.

The lawsuit does not provide any specific amount of how much overtime pay is involved. The city police bureau employs approximately 900 full-time officers.

No one could be reached at the city Law Department yesterday evening.
