<prompt> Human: Me and a Colleague share the work load, we have 10 sites in total and look after 5 each, When she leaves to have a baby i will be looking after all sites, we are getting in a temp to help me with the work load but i will have to train this person up on our procedures and she wont be doing as much as myself. The question i have is can i approach my manager for a pay rise during this period?  <response>: My company has a program called step up pay for situations exactly like this. Its temporary during the time you are affected. Worth asking anyway!?
