Yes, unless you have a contract with them that states otherwise, which you probably do not as most employment is "at will" and may be terminated by you or the company at any time with or without reason.
Yes, employees are typically entitled to receive their regular pay on legal holidays, unless otherwise specified by their employer or employment contract.
Employers must ATTEMPT to bargain a contract, but need not agree to union demands. Unions cannot get anything the employer will not give. No contract can require either party to violate a statute. COurts have almost nothing to do with bargaining - arbitrators and NLRB are enforcers.

The employer.
If your H1B employer is not paying your salary as agreed upon in your employment contract, it may be a violation of labor laws and you should seek legal advice or report the issue to the appropriate authorities.
