if you were fired from your previous job, keep it to yourself. Legally your previous cannot devulge anything nagitive toward you. Most employers look at your refs to see what you wrote, but honestly they rarly call the references, and if they do, legally all you previous employer do is conferm that you worked there and for how long, and what your job function was, they cannot legally answer any performance related questions, nore can the say why you left.
Employers can ask that in every state.
That depends on the employer.
That varies depending on the employer.
Not at all, if the former employer was disatisfied they have every right to inform future employer, if asked.
A person can ask their employer for a letter of reference for another employer. It is best to always be good standing with every employer.
In Canada you have the right to go to the former employer and ask to see your employee file and they have to accommodate the ex employee. However, what is in your file and what the former employer says behind your back are two different things. I always get a Letter of Recommendation from former employers because it covers your back. If they say anything else they would look like a complete fool because you have it in writing with your Letter of Recommendation. Employers don't have to give you a Letter of Recommendation, but give it a go. Every bit helps.
Sure. Vacation is not required, it purely an employer provided benefit.
It remains legal in every state to tell the factual truth about employees and former employees. "I fired Jim for attendance problems", can never be the basis for a defamation suit IF ... 1. I DID fire Jim, and 2. My reason was his absence record. Jim need not agree with my decision to make my statement factually correct.
Employers can sue employees in every state.
Probably, all most every employer does.
