About 300 workers at a Prince George, B.C., call centre will be working their last shift on Tuesday after a Dallas-based company decided to close its largest Canadian operation.

The workers were told in April that the company had lost its main client for the once-thriving operation, which used to handle three million calls a year at its central Interior location.

Since then, Affiliated Computer Services had been seeking a replacement client, but without success.

On Monday the company's Prince George general manager, Gurg Sarohia, confirmed that the vast majority of ACS's workforce would work their last day on July 14.

The workers will be competing for jobs in a city where the youth unemployment rate is already over 16 per cent.

Call centre worker Ross Wurm said he's still coming to terms with the news.

"Just gotta keep going. I just got off. I don't think it [has] really sunk in yet ... Hope it's not too hard to find work," said Wurm.

The latest layoffs are just another sign of the tough economic times, according to Francisco Cabanas, a job coach with the Prince George employment agency Jump on Board, which has been providing job counselling to the ACS workers.

"We're seeing an overall global economic downturn — and as a result we're seeing the impact right in our own city," said Cabanas.

The call centre's location in a once-thriving downtown neighbourhood is surrounded by boarded up storefronts, a drop-in centre for the homeless, and a soup kitchen.
