Depends on company, but most of those with RSUs generally give you every year refresher grants, each with another 4 year vesting schedule, so long as they are happy with your performance. Thus, if your initial grant was G0 shares, and refreshers each year are G_i, at each year you'd vest G0/4, (G0+G1)/4, (G0+G1+G2)/4, (G0+G1+G2+G3)/4, (G1+G2+G3+G4)/4, (G2+G3+G4+G5)/4, ... shares. Note the so called "cliff" after year 4, it's your cue to look for a new job. Especially if your initial grant was relatively large compared to refreshers as is often the case, but stock did not perform too well to compensate for it. Size of refresher grants depends on your level, review and stock performance - company usually has some target $ amounts in mind for them.
