How can I find the monodromy of a cyclic galois cover of the affine line minus a few points?

Consider the following cyclic covering of the affine line minus a few points: $$ \text{Spec}(\mathbb{C}[t,x]/(x^n - t(t-1)(t-2))) \to \mathbb{A}^1_t - \{ 0, 1, 2 \} $$ How can I find the local monodromy representations around one of these points of degeneracy?
