An employee in a government electricity company is concerned about their job security after completing 9 years of service. Despite initial probation and a subsequent one-year suspension for a departmental inquiry (which concluded with a minor penalty), the employee was never formally notified of any probation extension or termination. Now, as they approach higher pay scales, the company is suggesting they can extend probation or terminate them based on past 'C' and 'D' grade ACRs during their initial probation. The employee seeks clarity on whether the company can retroactively extend or terminate their employment after such a long period without prior communication.
