My company co-organises lots of events and if the events are of technical nature, we as employees, get promo codes that allow us free entry. One such event is being organised in a couple of weeks. What is different this time is that I put in my notice and I will be leaving the company. My last day is a couple of days before the event. The code was given out recently and I am planning to use it to enter it.
How unethical would that be considered? I am leaving on good terms with everybody. I am taking a month off so I won't be employed yet when the conference takes place.
