Access to timesheets is driven by your employment settings in your company's payroll platform. If you believe you should have access to timesheets and you do not, please contact your systems administrator to ensure they have set you up with the access required.
If your systems administrator confirms they have set you up with this access and you still cannot access timesheets. Try the following:
Restart your EH Work app;
Check for updates in the app or Google Play store;
Sign out and back in; and
Uninstall and then reinstall the EH Work app.
