Yes. Among the employees that must be put into a workplace pension, there are some exceptions. Your employer can choose whether or not to enrol certain employees if:

• they’ve handed in their notice (unless they take it back later)
• they’ve stopped membership of the automatic enrolment scheme into which they were  enrolled within the last 12 months
• they benefit from some kind of tax protection on their pension savings
• in the last 12 months they’ve received what’s known as a ‘winding-up lump sum’ and are re-employed by the same employer.
