On call coverage at our workplace has been largely voluntary, with it being built into 2 positions. Recently there has been a lack of volunteers due to low compensation, the draw on personal time, low staff, and does not aid in professional development (does not lead to promotions). Now there is talk about forcing positions that have never had any on call component, to be on call. My question is, what are our rights in regards to this? Can they do this? And can we say no without repercussions? We are in AB. Thanks!

The general rule is that an employer cannot make changes to fundamental terms of employment unilaterally. Arguably, on-call coverage can be onerous and therefore a fundamental term of employment. Imposing it without the employee's approval could constitute constructive dismissal and trigger the employee's termination entitlements. Your initial response could be to reject adding on-call coverage to your work schedule but if the employer persists then you should contact us for a consultation before you make a final decision.
