how do I get a job as a morgue assistant
You could probably take some classes in biology and science that would help you get you in the door.
I hear that people are "dying" to get in! LOL!
No, seriously, I wish you the best.
PS. If you do go into this field you can expect a lot of joking related to death...
go to your local morgue and ask if you can do a job shadow. find out if that is something you would really enjoy doing. Make sure you have good PR skills...just kidding") interesting career interest though.
go to the morgue and ask them the requirements needed and them make a resume and hand it to them
why do you want to?
