In the month of June I was fired from my job. A month before they talked to me because I was part of a group chat whatsapp from my old job. I decided to share new thing without bad intentions. My mistake was that thing i shared had a personal phone number which Im not supposed to share because is private. They talked to me and I told them that I know I acted unprofessional but never with bad intentions. They never gave me a memo or nothing they said ok. Who did they know? An ex- coworker decided to send those to HR or my ex manager. She went to same interview as me but she did not got hired and I know she did it on purpose. A month after they decided to fired me because of that situation which they said I could appeal it. I wrote a letter to HR explaining why I would deserved a second opportunity and 3 days after I called them and they said they would call me back but never did. After 2 months I send them another email but again no response and this is a big recognize company. I never told them I was bullied inside, I don't want them to think I am mention it just to get them. Should I put them as a reference for others job? Should they have answered me? Should I keep trying?
