A: Generally, in Florida, severance is a gift. $1 of severance is usually $1 more than an employer is obligated to provide. An offer of severance may be required if an employee has an employment agreement providing for severance or is otherwise subject to a collective bargaining agreement that provides for severance.
Severance agreements that are only offered to certain employees in a discriminatory manner (such as based on age, religion, national origin, sex, etc) may be a violation of local, state and/or federal law.
A: The National Labor Relations Act prohibits an employer from engaging in retaliation against two (2) or more employees who band together to for mutual aid and protection, including raising concerns about lack of pay details.

Florida Whistleblower Act, Fla. Stat. 448.102 provides whistleblower protection for employees who are retaliated for raising certain concerns in the workplace: http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0448/Sections/0448.102.html
