new job - nervous what happens after interview

[charlottenina]

went to interview but they did not say when they woudl call me. this is part time position and iit is 3 days a week. they have a variable clause - that it may change less or up within 20 percent....Can i negotiate that I can only go up hours, not less, so delete the "less 20 per cent" from the clause?

i just cannot afford working less than 3 days a week

You can ask, but it will depend how keen they are on you, how important that clause is to them and how many other good candidates they have as to what they'll say.
