Is this a do or don't?
Most job applications throw in questions about whether it's OK to contact your current workplace (and if it isn't they make you explain why).
My thinking is this is nobody else's business. What happens if you don't say anything to your boss, but the boss somehow finds out, you end up not getting hired and then are stuck working at the same job with a boss who now feel like you're untrustworthy, etc. Not saying I agree with this at all, as it's a shitty thing to hold against a person who just wants to better him or herself.
What do you all think?
