Have I resigned?

[Limaoska]

Hello all, I wonder if there are any HR experts around who might be able to answer my question?
I work/worked as a delivery driver for a large supermarket chain. The vans are all fitted with telemetry and CCTV. At the beginning of July we had all the old vans replaced with a new fleet. In late July I was “clocked” at 58mph in a 40mph zone and because of that was invited in by the dept manager for a disciplinary meeting which took place on the 30^th of July. The upshot of the meeting was that the decision to either give me a written warning or dismiss me was being passed further down the line.
I questioned the evidence re the speeding and was told that the van takes a reading 20 metres past where the road sign is located and at that point it showed I was speeding. Of course I asked if there was any other evidence to corroborate the GPS ping and was told there was not. So basically they were looking at officially warning me/dismissing me based on one flimsy piece of evidence. The other fly in the ointment is that since the new vans were introduced I am one of eighteen drivers who are being investigated for alleged speeding. It raises the question are the vans accurate/calibrated correctly?
Anyway, the upshot is I was stressed and angry on the night (certainly not in the right frame of mind to deliver shopping) so I threw my teddy out of the cot and walked out leaving behind my clock cards and some items of uniform.
I did not give any notice to anyone that I was quitting nor sign any resignation.
And that was it…..no further contact from anyone at the company until I received a letter on the 7^th of August asking me to fill in a post employment interview form following my immediate resignation on the 30^th of July.
Can anyone answer whether what they have done is lawful? Yes I know it was not the best way to handle the situation but I did not sign anything about resigning, and was not spoken to after the incident by any person from management or HR about my status.
Sorry to drone on with my first post.

In terms of timing of events and what has happened since can you provide some further information by answering the following questions which will help me provide a response.

Did you walk out on the 30th July after the meeting?
Did you tell anyone you were leaving and would not be working?
Have you been due to work since you walked out?
If so have you worked or if not have you been in contact with your employer?

Many thanks

Hi, Yes I did walk out after the meeting on the 30th. I spoke with one of the driver support staff and told him I was leaving and would not be making deliveries. As I said I was very angry at the time. I should have gone back on the 31st but did not, and as mentioned I have not been in contact with anyone from the store since.

I think then, given your actions, the company has probably thought that you have left. It would have been good practice for the company to try and make contact with you, but given you did not speak to a manager when you left you cannot be sure what message was given by the support staff person about your departure.

I think you have to make the decision as to whether to want to move on from this job or get in contact with the company and have a conversation with them about the incident that led you to walking out and see if that can be resolved.

Thank you for taking time to reply. I think given the poor management at the store I will move on.
