My wife has been told she has 8 weeks of working notice but her boss wont put it in writing even though she's asked more than once. This is totally stressing her out as she doesn't truly know where she stands.

Working notice implies termination of employment which is generally announced by way of termination letter. Whether or not your wife receives a termination letter, I encourage her to call me at 416-216-5906 to arrange a consultation. Lumi Pungea
