The standard here in Texas, an "at will" employment state, is to give two weeks notice. In Texas we are under no obligation to accept the two week notice and it is still considered a resignation because they demonstrated intent to leave.Please accept this letter as my formal resignation. Have the employee fill out a resignation letter in her own words, preferably in her own handwriting, if you can so persuade her. Resigning is one of the final steps in the process of accepting a new job. But first, resignations in Texas. Second paragraph: You can explain why you're leaving in the second paragraph, but keep it brief and professional. Explain why you are resigning.
