So keeping written evidence of everything that happens at work is arguably the best legal defense you can have in order to avoid your boss or HR taking advantage of you. Asking for certain instructions and deadlines to be delivered via e-mail instead of just verbally is a good example of this. However, my suspicion is executives and particularly Human Resources (I don't know how it is in other countries, but here in México it has the infamy of being the most crooked department you can find) are hyper aware of this and avoid falling into that “trap.” So, what are some sneaky tactics I can employ in order to keep a paper trail of everything and protect myself legally in the workplace, should the need arise?
