Apologies it's a long one.
I was fired on the spot from my job last week. It's all still very raw. It was a good job I planned to stay in for a long time. I had been there just over a year and really enjoyed it.
The only difficult part of the job was working with a colleague who openly despised me from day one. Although she never made it clear why, I put it down to the fact that I was more qualified than her and younger but had more responsibility. She made regular attempts to undermine me and sabotage my work.
It all got very heated on a Friday. She'd made an error which I had to fix and when she asked why I'd interfered and I explained, she became irate. She screamed in my face and told me she would get me fired because she was sick to death of seeing my face. Unfortunately no one was around to hear this as it was after everyone had gone home.
I planned to go in early on Monday and report her to the boss as I was very shaken by the encounter. When I arrived the boss was in meetings for two hours. I then found out that she'd been out with my colleague for coffee for an hour before the meetings, which is unheard of.
After her meetings, I was called into the office via phone. The boss's secretary was there to take notes. The boss said she was really disappointed in me because she had heard that I'd told my colleague no one liked her and not to bother coming back to work (untrue). Colleague now felt like she couldn't work with me and threatened to leave. Boss said as colleague had been there longer (3 months longer) I should be the one to go.
I was in utter disbelief and asked for clarification if I was being fired. Boss said 'yes there's no other option but we'll pay you your notice period if you leave the building immediately because Colleague has her things packed ready to leave if you don't'.
I wasn't given the opportunity to give my side of the story as I was escorted out. I then received a Facebook message from colleague that said 'told you I'd get you fired 
'.
I called acas who told me to check my contract. It says 'all employees are subject to disciplinary procedures outlined in the staff guide.' I got hold of the guide and it confirms that all employees, regardless of length of service and including staff in their probationary period will be subject to the procedures outlined. It then has a very clear structure for both misconduct and gross misconduct that wasn't followed at any stage.
Acas have told me I have a claim for wrongful dismissal based on them not following their own guide and not offering me a representative.
I now have to write to them but I'm so exhausted by it all I'm questioning if it's worth putting myself through it.
What would you do?
