I am resigning from my position in Massachusetts. I gave 3 weeks notice, but my employer is telling me that I am required to give 4 weeks notice.Wait until the contract is signed. Then give a reasonable and acceptable notice to your current employer. Massachusetts law about hiring employees. Laws, regulations, cases, and web sources on hiring employees law. When you write a letter of resignation, you have quit. Offering to stay two weeks is the standard in an effort to help transition the work etc. An employer cannot force an employee to work. Conceivably, if the 30 day notice period is part of a contract, the employer can claim breach of contract.
