I work in the Canada office (Ontario) of a large US tech firm. The firm has had a few lackluster quarters, and appears to be preparing for a few rounds of layoffs.
My company, AwefulCorp Inc. (made up name), apparently created a new company (i.e. separate incorporated company, FakeInterviewers Inc), and is reaching out to people at AwefulCorp Inc. requesting phone/Skype interviews with them to see if they'd be interested in a career opportunity. However, it appears these job offers are not necessarily sincere (I can't be 100% sure), and they are strictly being used to identify disgruntled employees that are "flight risks", so those employees can be targeted for layoffs.
Edit: we can confirm by looking at the business registration and domain name registration for both companies, and we personally saw an HR employee at our office answering a phone and claiming to be an interviewer from FakeInterviewers Inc. We are dead sure of this.
Is this allowed in Canada or the US? We created some fake LinkedIn profiles with silly/obscene-sounding names, claiming to be employees of this company (even got into a couple Skype interviews, surprisingly). They talk about "great benefits", and after a lengthy discussion, low-ball on the salary by a lot.
