Counsellors with Many Rivers Counselling and Support Services in Yukon have given notice that they’re ready to strike for a new contract.

Members in Whitehorse, Watson Lake, Dawson City and Haines Junction voted 83 per cent in favour of the strike action.

Union president Steve Geick said the vote comes after a conciliator failed to reach a deal with the counsellors on flexible work hours.

"When they're put into a situation where someone is in a crisis and they have to work before or after regular work hours, they've been allowed to flex that time. So they're not looking for overtime, what they're looking for is the ability to continue to bank those flex hours and take them at a later date," said Geick.

The strike mandate means the 18 members of the union can walk off the job on Friday if no deal is reached. The employer, Many Rivers Counselling, can also lock them out.

In a news release, the union said it’s optimistic that a deal can be reached by then, although no talks are scheduled.

Many Rivers Counselling and Support Services is a non-government agency which is run by a board of directors.
