An employee and employer may agree a period of unpaid leave for reasons that are entirely understandable. Immigration sponsorship introduces a separate question: whether the Home Office permits the sponsor to continue supporting a worker whose paid employment has paused or fallen below its normal level.
The current sponsor guidance does not impose an absolute ban on every absence exceeding 4 weeks. It establishes a general rule, identifies specific exceptions and requires sponsors to keep the reporting and evidential position under control.
