Learning the future tense is a great (and relatively simple) way to improve your grammar and confidence in Spanish. While there is more than one way to communicate in the future, I recommend beginners start with:
Voy a trabajar = I will work
Vas a trabajar = You will work
El / Ella va a trabajar = He / She will work
Van a trabajar = They will work
If you want more examples of how to simplify Spanish grammar, book in a class ASAP and I will pass on all my tips and tricks.
