What's your salary requirement?
A prospective employer DOES have the right to ask about your employment history.
Yes this is legal if you are already and employee of the company or person they can deny your application for interview.
Yes. The legal implications would only be if they lied and caused you harm.
They can't ask this question in this manner. A way around may be for the employer that is hiring you to ask the previous employer are you re-hireable. In most cases they only verify dates of employment and salary for legal reasons. This is the general practice.
That would be entirely up to whatever their prospective employer does, or does not, offer as part of their employment package.
The only questions that are truly legal are if the employee worked their and what their position was. They can also ask if they are eligible for rehire.
An employer cannot base their hiring decision on whether or not a candidate is taking prescription medication. As a matter of fact, this is not a legal question for an employer to ask on and application or during an interview.
As an employer, you need to insure that your prospective hire has a legal right to work in the United States. If the person is not a citizen, then you need to find out if you can provide a legal visa for the employee. If not, then you have to terminate her.
There is no legal restriction on their employment in this field. Whether or not they are employable is entirely up to the diecision of any prospective employer.
Because everybody deserves a fair chance at a job, and it would be unconstitutional if they didn't allow that person to do that.
This is a legal question which WikiAnswers does not engage in. It's best asked of an attorney or legal aid society.
