I'm not an expert on ATIP laws, but I could tell you for whistle-blowing laws definitely there are consequences. One of the consequences is that the company, if they are taking an action against a whistle-blower, essentially has to continue paying that whistle-blower's salary for as long as they want to. So there's a financial cost for them there, and there's also in some countries a criminal sanction.
Criminal sanctions are harder to prove, because you have a higher standard of proof, so you might want to go with something like administrative monetary penalties or something like that.
