From Maintenance to chemistry??

[MrKilljoi]

So I have recently got a job as a maintenance technician and I was wondering is it unheard of for a mechanical maintenance technician to eventually transfer to a job as a chemistry technician, Is it even possible without acquiring a degree first?

At most places, in order to apply from within, you still have to meet the minimum requirements for the position.
If they reqire a degree (and don't have an entry level training program) you will likely not be considered.
