Hi all,
Thanks very much for your responses, much appreciated:
@Hodgman- that's great at least I have method to negotiate or not.
@braindigitalis- Ah that's such a shame your boss reacted that way, glad your efforts are now appreciated. Fortunately my boss knows all about it and is completely on board all of the department use the software. I work in the computer science department so we work quite closely with the network technicians, you guys have a tough job :)
@Tom Sloper- It's a school, all of the contract details are around teaching and learning, theres nothing software development in there.
@BrianRhineheart-
Was your employer from public or private sector?
>>Public sector, UK state school
Does your official work duties include writing software?
>>No, my duties are all about teaching my subject
Did you write the software during paid working hours?
>>Yes I did
Did you uninstall the software before you left?
>>No, It's a bunch of python scrips, the user can copy them to their folders and run the program, so there is nothing to uninstall. I don't leave until the summer so I have some time to work out what to do. I was thinking of putting the program on the cloud and charging a yearly subscription which would also cover any maintenance that needs to be done.
I'm not looking to get rich, I'm just trying to work out what the fairest thing to do. I built the software and it's saving users a lot of time, If I no longer work there and people are still using my work is it not right that i get compensated for this ?
Thanks again for your inputs
