Hi Leslie, The rule we're looking at here is "causative verbs". There are only four! Let, have, help and make. The pattern is this: [causative verb] + [object] + [base verb] ...so the second verb is always in the base form. So, [make] + [my money] + [work] ... Here's a slightly adjusted sentence, so the form of the first verb doesn't confuse you. "This investment plan makes my money work for me." The conjugation has already happened, so we don't do anything to "work" (which, anyway, is connected to the object - money - and not the subject).

It's definitely not conditional. ;)

So is it conditional or causative? Very interesting set of answers. Everybody thank you so much for your input.

Make my money work for me. First of all, this is a command so the "work" in "..my money work.." is conditional. My money works for me. This is a statement, work is not conditional.
