Not unless your employment contract specifically states that he does.
One exception might be if you go on certain types of leave (maternity leave, for example), though it's not so much that the employer has to keep your specific job open as that there has to be a comparable job available for you when you return. In the US, nearly all employment is "at-will", which means your employer can fire you for any reason or no reason at all, so long as he's not actually discriminating against you (if he fired all the black employees, for example, that would not look good, but if he fired everyone who had been with the company for less than six months, that's perfectly fine).
he must keep it open till you are fit to return and why not ,you dont go to work to get injured would your boss
If you leave the employers job, UNLESS he signed a contract with you to provide such services regardless of your employment status with him. he owes you no further obligation to retain you in a training position.
ABSOLUTELY. I just went threw this with my employer. It is Federal Law and they HAVE TO keep your job for you.USERRA fed law says the employer must allow you to go. It need not keep your job open, but must return you to your job - firing your replacement - if you return within five years. Keeping your job unfilled for years would lower productivity, and no law requires that.
my current job is teaching geology and i have applied to do seimic survey
That depends on what "disability leave" you took. If the employer granted you FMLA leave, then you must be restored to your old job (or a job EXACTLY like it) even if the employer must fire some one to create the vacancy. If you were just off sick or injured, you have no right to your job back, unless found in a union contract. Employers own the jobs and hand them out as they wish - the job is not "yours", but theirs.
Exactly what is stated, he/she 'might' their current employer to seek work for a different employer.
the amount of time you have spent with the company
First, have a previous job. Next, leave that job for some reason. Now, explain why you left your previous job to your prospective employer. It's simple. Be honest. It's what they want from you.
I got fired from a job do i get my profit sharing
The employer will assume an employee has stolen something from the company.

There are two law that provide job security during your leave for disability: the FMLA provides twelve weeks of unpaid leave for your disability. NJ has a separate law, but it provides leave for you to care for a sick family member - not your own disability. Your employer does not have to hold your job open if FMLA does not apply, or if your leave extends beyond 12 weeks.
