Discipline - already issued

• Can an AFSCME employee on discipline apply for an unclassified position? How about another AFSCME position?
• I was hired in November, so I believe I'm still in a six-month evaluation period. What are my rights and responsibilities in terms of layoff or discipline? Thanks!
• If a manager needs to coach an employee and possibly discipline them do they need to let the union know before they do anything?
• Can I be disciplined for off duty conduct?
• What is insubordination?
• If an employee receives a "verbal warning" does the manager/supervisor need to verbally speak to the employee regarding this disiplinary action? Does putting a written copy in an employees mailbox, where other employees can see it, or sending it via e-mail constitute a valid verbal warning?
