Pausing an employee's contribution will not allow contributions to be pulled for this person until the admin decides to reactivate them. Effectively, no money will be put into their Wealthsimple Invest account during this period.
To pause an employee, head to the Employees section and use the search function to find the desired employee. Once you select the employee's name their employee details page will populate.
Scroll down to see the option to pause or reactivate an employee depending on their current state.
