B.C. paramedics could be on strike by early Wednesday morning after voting Saturday to give 72-hours strike notice.

B.J. Chute, a spokesman for the Ambulance Paramedics of B.C., said strike action would escalate, but initially could include a ban on voluntary overtime and administrative tasks like billing.

According to media reports, paramedics are asking for between four and 4.5 per cent per year, over seven years. The government has offered a one-year deal worth three per cent, with signing bonuses to bring it up to six per cent.
