Sounds more like a bad company problem than a bad hire problem. If management is always nervously looking at the clock, then the company is fundamentally rotten. You get what you measure. If you measure hours at work, then you will get people who pad their time while they produce a pile of crap. Nevertheless, this Canadian employer should know better. In the first three months they can let people go instantly. If they aren't confident in the person after a few days, show them the door.
