GUILDERLAND — The town has workers in four unions; each union has a contract set to expire at the close of 2010. Each current contract outlines a stepped system, where workers are paid more for every year they work.

The Enterprise has reviewed the contracts and the salary ranges are as follows:

— Civil Service Employees Association Unit A, which outlines three positions, includes the director of animal services, who starts at $40,807 annually, and makes $50,047 after five years; a tele-communicator, who starts at $34,677 annually, and makes $42,854 after fives years; and a senior tele-communicator, who starts at $51,003 annually, and makes $63,365 after five years;

— CSEA Unit B, with 27 members, includes 21 positions, which range from a courier’s starting salary of $20,675 that goes to to $25,461 after five years, to a building inspector’s starting salary of $39,291 to $49,155 after five years. Unit B also includes positions paid by an hourly rate rather than an annual salary: a custodial worker with a starting hourly rate of $11.72 and a rate of $14.04 after five years, and a senior citizen bus driver with a starting hourly rate of $12.56 and a rate of $17.05 after five years;

— The Guilderland Police Benevolent Association has 34 members; pay schedules are set according to rank: Officers make $44,702 upon hire in 2010, $71,125 after five years, and $74,603 after 18 years; senior patrol officers make $57,602 upon hire and $77,062 after 18 years; sergeants make $73,488 to start and $84,057 after 18 years; first sergeants make $75,205 to start and $85,239 after 18 years; detectives make $45,547 to start and $76,448 after 18 years; and senior detectives make $50,164 to start and $80,064 after 18 years. There are wide discrepancies among officers’ salaries, because some take on overtime, which the town supervisor has tried to cut back on, but he says some can’t be avoided. The Guilderland Police Department paid five of its officers over $100,000 in 2010; the police chief’s salary was $89,961. Other salaries ranged from $61,207 to $119,599; and

— The United Public Service Employees Union, which has members of the Guilderland Emergency Medical Services, includes full-time employees, who make $38,050 upon hire and $45,405 after five years, and part-time employees, who make $20.32 per hour upon hire and $24.25 per hour after five years.
