- Do you have much work to do? (= work that you must do)

Compare for ... and to ... :
| for + noun |
to + verb |
| We stopped for petrol. |
We stopped to get petrol. |
| I had to run for the bus. |
I had to run to catch the bus. |
You can say 'for somebody to do something':
- There weren't any chairs for us to sit on, so we sat on the floor.
You can use for -ing or to ... to talk about the general purpose of something, or what it is generally used for:
- I use this brush for washing the dishes. or ... to wash the dishes.
But we do not use for -ing to say why somebody does something:
- I went into the kitchen to wash the dishes. (not for washing)
You can use What ... for? to ask about purpose:
- What is this switch for?
- What did you do that for?

| D |
So that
We use so that (not to ... ) especially
when the purpose is negative (so that .. . won't/wouldn't):
- I hurried so that I wouldn't be late. (= because I didn't want to be late)
- Eat something now so that you won't (or don't) get hungry later.
with can and could (so that .. . can/could):
- She's learning English so that she can study in Canada.
- We moved to London so that we could see our friends more often.
You can leave out that. So you can say:
- I hurried so that I wouldn't be late. or I hurried so I wouldn't be late.
